How Do I Read Filenames from a Folder and Add Them Into an Arraylist Without Having to Make an Array and Looping all the Answers Into the Arraylist? : For example, say I have a list of .txt files in a folder. What do I need to do in order for Java to read through each of the names of each file and add them into a string array list without having to do a String[] like other answers have suggested?

Does exists "with" keyword (or default method) on java? : I'm working on a code when I notice the following "with" keyword on the constructor and I wanted to know what kind of constructor (or technique) is this, and how to use it.
public static Database with(String key) {
if (sInstance == null) {
sInstance = new Database(key);
}
return sInstance;
}
And one usage of this is:
mDatabase = Database.with(User.listAll(User.class).get(0).getKey());

Part of code execute every 5 minutes C++ : I am try to implement wait in c++. I cannot use sleep since it stop the current execution.
For eg.
do
{
if(something)
{
//Do something
}
if(something)
{
//Do something
}
if(every 5 minutes)
{
//Do something only once after 5 minutes
}
}
while(true)
I cannot use sleep since it will stop the execution. Can you help me with this since I need to implement this in this do while loop. I would have used threads with detach but I want to this 1 a single do while loop.

calling a parameterized constructor using 'this' instance c# : class manning
{
public int i = 0;
public manning() : this(this.i)//why is this not possible.
{
this.i++;
Console.WriteLine(i);
}
public manning(int i)
{
i++;
Console.WriteLine(i);
}
}
1.Hi in the above code while calling the parameterized constructor why can't i can use 'this' keyword as the way it is declared.
2.it actually gives me an error stating that-"An object reference is required for the non-static field, method, or property".which can resolve by making 'i' declaration static.but 'i' variable got initialize when constructor is invoked using new.
please help me understand why above code is not possible.
thanks.

PHP - use of variable : <p>I want my PHP code to display one out of N .txt files on my webpage. (If I visit example.com/index.php?l=1 it should display 1.txt) I´m using a variable for the numbers called $m. $m is defined correctly as it is working on other pages.</p>
<p>My problem is that I can´t define the location of "1.txt" with a variable. My code is:</p>
<pre><code> $filename = "C:\xampp\project\Logs\.$m.'.txt';
if (file_exists($filename)) {
if (is_readable($filename)) {
$handle = fopen($filename, 'r');
if (filesize($filename) > 0) {
$contents = fread($handle, filesize($filename));
fclose($handle);
$contents = str_replace('\r\n', "\r\n", $contents);
echo ' <textarea data-autoresize class="form-control vresize" id="info" rows="20">'.$contents.'</textarea>';
} else {
echo ' <textarea data-autoresize class="form-control vresize" id="info" rows="20"></textarea>';
}
}
} else {
echo '<br><font color=red>Cant get any Logs for ID: '.$m.'</font>';
}
</code></pre>
<p>I tried a few different things but nothing worked out for me because $m does not get resolved in $filename.</p>
<p>Was anybody able to follow my description and understands my problem? Help is very appreciated!</p>

"Undo" canvas transformations for writing text : <p>When applying a transformation with canvas, the resulting text is also (obviously) transformed. Is there a way to prevent certain transformations, such as reflection, of affecting text?</p>
<p>For example, I set a global transformation matrix so the Y-axis points upwards, X-axis to the right, and the <code>(0, 0)</code> point is in the center of the screen (what you'd expect of a mathematical coordinate system).</p>
<p>However, this also makes the text upside-down. </p>

What's wrong?

What is ViewModelStore and viewModelStoreOwner? : <p>I am very confused due to this new ViewModelProvider api(ViewModelProviders is deprecated) </p>
<p>As with the new changes there are new Constructors also (Source code). </p>
<h3>#1</h3>
<pre><code>public ViewModelProvider(@NonNull ViewModelStoreOwner owner) {
this(owner.getViewModelStore(), owner instanceof HasDefaultViewModelProviderFactory
? ((HasDefaultViewModelProviderFactory) owner).getDefaultViewModelProviderFactory()
: NewInstanceFactory.getInstance());
}
</code></pre>
<h3>#2</h3>
<pre><code>public ViewModelProvider(@NonNull ViewModelStoreOwner owner, @NonNull Factory factory) {
this(owner.getViewModelStore(), factory);
}
</code></pre>
<h3>#3</h3>
<pre><code> public ViewModelProvider(@NonNull ViewModelStore store, @NonNull Factory factory) {
mFactory = factory;
mViewModelStore = store;
}
</code></pre>
<h3>Gradle Depenedency:</h3>
<pre><code>implementation "androidx.lifecycle:lifecycle-extensions:2.2.0-rc02"
</code></pre>
<p>So These Constructor's require <code>ViewModelStore</code> and <code>viewModelStoreOwner</code>.</p>
<h3>Doc:</h3>
<blockquote>
<p>@param store {@code ViewModelStore} where ViewModels will be stored.</p>
<p>@param owner a {@code ViewModelStoreOwner} whose {@link ViewModelStore} will be used to
retain {@code ViewModels}</p>
</blockquote>
<hr>
<p><strong>Can anyone define them and how to use them and what they really mean to us developer's?</strong></p>
<hr>
<p><strong>is ViewModelStoreOwner==activity/fragment?</strong></p>

Google App Engine 502 (Bad Gateway) with NodeJS : <p>I have a full web application using NodeJS, MongoDB (Mongoose as the driver) and ExpressJS.</p>
<p>The project works perfectly on my local machine. Today I decided to move everything to production. I'm using Google App Engine to host my application, and Compose (formally MongoHQ) to host my database.</p>
<p>App Engine servers my application perfectly, although my API does not seem to work. My API is served from <code>example.com/api</code>, and each request (<code>GET</code>, <code>POST</code>, <code>DELETE</code> and <code>PUT</code>) all returns a 502 (Bad Gateway) error.</p>
<p>I tried running my application on my local machine while connected to my remote MongoDB database and that worked perfectly fine. So it must be a problem with App Engine or NodeJS, not with MongoDB.</p>
<p>I have tried checking all error logs within Google Cloud, although there are no errors.</p>
<p>Why is App Engine/NodeJS serving my application's static content perfectly fine, although not allowing any requests to my API?</p>

Detach ItemTouchHelper from RecyclerView : <p>I have a RecyclerView with a working ItemTouchHelper. Everything works great, but I am wondering if there is a way I can detach the ItemTouchHelper from the RecyclerView without re-creating the list? For fun, this is the code I'm using to attach:</p>

{
...
};
mItemTouchHelper = new ItemTouchHelper(callback);
mItemTouchHelper.attachToRecyclerView(mPasswordList);
</code></pre>
<p>Ideally, I'd like to check a preference in say <code>onResume()</code> of the Activity this RecyclerView lives in and detach the ItemTouchHelper based on that.</p>

Getting DOM node text with Puppeteer and headless Chrome : <p>I'm trying to use headless Chrome and Puppeteer to run our Javascript tests, but I can't extract the results from the page. Based on <a href="https://stackoverflow.com/a/45799744/4794">this answer</a>, it looks like I should use <a href="https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pageevaluatepagefunction-args" rel="noreferrer"><code>page.evaluate()</code></a>. That section even has an example that looks like what I need.</p>
<pre><code>const bodyHandle = await page.$('body');
const html = await page.evaluate(body => body.innerHTML, bodyHandle);
await bodyHandle.dispose();
</code></pre>
<p>As a full example, I tried to convert that to a script that will extract my name from my user profile on Stack Overflow. Our project is using Node 6, so I converted the <code>await</code> expressions to use <code>.then()</code>.</p>
<pre><code>const puppeteer = require('puppeteer');
puppeteer.launch().then(function(browser) {
browser.newPage().then(function(page) {
page.goto('https://stackoverflow.com/users/4794').then(function() {
page.$('h2.user-card-name').then(function(heading_handle) {
page.evaluate(function(heading) {
return heading.innerText;
}, heading_handle).then(function(result) {
console.info(result);
browser.close();
}, function(error) {
console.error(error);
browser.close();
});
});
});
});
});
</code></pre>
<p>When I run that, I get this error:</p>
<pre><code>$ node get_user.js
TypeError: Converting circular structure to JSON

<p>The problem seems to be with serializing the input parameter to <code>page.evaluate()</code>. I can pass in strings and numbers, but not element handles. Is the example wrong, or is it a problem with Node 6? How can I extract the text of a DOM node?</p>

Why warnings prevent us from writing optimized programs? : <p>Check out this code:</p>

unsigned short GetShort_With_Warning( unsigned long long val ) {
return *(unsigned short*)&val;
// mov ax,word ptr [val] // That's it. Elegance
}
unsigned short GetShort_Without_Warning( unsigned long long val ) {
unsigned short* shv = (unsigned short*)&val;
// lea eax,[val]
// mov dword ptr [shv],eax
return *shv;
// mov eax,dword ptr [shv]
// mov ax,word ptr [eax]
}
int main( void ) {
printf( "%04x\n", GetShort_With_Warning ( 0x101234ULL ) );
printf( "%04x\n", GetShort_Without_Warning( 0x101234ULL ) );
return 0;
}
</code></pre>
<p>This is just an example...<br>
There are two functions that do the same, but one gives a warning and the other does not. The assembler code is shown with a comment. Can it be made that the 'elegant' decision does not give a warning?</p>
<p>It's compiled with g++:</p>
<pre><code>g++ -Wall -O3 -s -I. -c -o main.o main.cc
</code></pre>
<p>The following warning appears:</p>
<pre><code>main.cc:4:28: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
return *(unsigned short*)&val;
^~~
</code></pre>
<p>I know what the warning wants to say me.<br>
I know that with today's CPU power this case is not a problem.</p>
<p>Anyway...
My question is why the warnings don't allow me to optimize my code?</p>

How do you add migrate an existing database with alembic/flask-migrate if you did not start off with it? : <p>This is the chain of events that has and is happening</p>
<ul>
<li>Day 0: I developed and deployed my app </li>
<li>Day 1: I create the new database </li>
<li>Day 3: I realized I wanted to add a new row to my existing table. I found flask-migrate and I want to use it to migrate my database.</li>
</ul>
<p>Currently I am at Day 3</p>
<p>There are plenty of documentations on how to get Flask-migrate running if you start from Day 0. You just call <code>flask db init</code>, <code>flask db migrate</code> and <code>flask db upgrade</code>. </p>
<p>However, for my case, it's a bit different. I ran the commands, and my first version of migration is <em>empty</em>. Then I modified my database schema and generated a new migration. Now my latest migration only has 1 line of migration which is adding the new row to the table. </p>
<p>I realized that none of my migrations have the actual schema to create the database, which is supposed to be the first migration you see if you start flask-migrate on day 1.</p>
<p><strong>If I were to clone my repo from scratch:</strong> </p>
<p><code>flask db migrate</code> will result in <code>alembic.util.exc.CommandError: Target database is not up to date.</code>. </p>
<p><code>flask db upgrade</code> will result in <code>sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) relation "offer" does not exist</code>. </p>

what do lseek and offset do : <p>Can someone explain me what does this program do? I can't understand. I created a file named "FILE" and I wrote a five-letter word on it. Now, what does this program do? I don't understand what the offset is... Please explain me, I know it's easy concepts but I can't seem to understand it... Thanks.</p>
<pre><code>#include <sys/types.h>
#include <fcntl.h>
#include <sys/stat.h>
#include <unistd.h>
int main(void)

int fd,i;
fd=open("FILE",O_RDONLY);
i=lseek(fd,50,SEEK_CUR);

python pandas sum by hour of day : <p>I'm working with the following dataset with hourly counts (df):
The datframe has 8784 rows (for the year 2016, hourly).</p>
<p><a href="https://i.stack.imgur.com/4wvBM.png" rel="noreferrer"><img src="https://i.stack.imgur.com/4wvBM.png" alt="dataframe (df)"></a></p>
<p>I'd like to see if there are daily trends (e.g if there is an increase in the morning hours. For this i'd like to create a plot that has the hour of the day (from 0 to 24) on the x-axis and number of cyclists on the y axis (something like in the picture below from <a href="http://ofdataandscience.blogspot.co.uk/2013/03/capital-bikeshare-time-series-clustering.html" rel="noreferrer">http://ofdataandscience.blogspot.co.uk/2013/03/capital-bikeshare-time-series-clustering.html</a>). </p>
<p><a href="https://i.stack.imgur.com/vo2Qo.png" rel="noreferrer"><img src="https://i.stack.imgur.com/vo2Qo.png" alt="enter image description here"></a></p>
<p>I experimented with differet ways of <code>pivot</code>, <code>resample</code> and <code>set_index</code> and plotting it with matplotlib, without success. In other words, i couldn't find a way to sum up every observation at a certain hour and then plot those for each weekday</p>
<p>Any ideas how to do this? Thanks in advance!</p>

How to use servlet 3.1 in spring mvc? : <p>There are 2 different features available:</p>
<ol>
<li><p><strong>servlet 3.0</strong> allows to process request in a thread different from the container thread.</p></li>
<li><p><strong>servlet 3.1</strong> allows to read/write into socket without blocking reading/writing thread</p></li>
</ol>
<p>There are a lot of examples in the internet about servlet 3.0 feature. We can use it in Spring very easily. We just have to return <code>DefferedResult</code> or <code>CompletableFuture</code></p>
<p>But I can't find example of usage servlet 3.1 in spring. As far as I know we have to register <code>WriteListener</code> and <code>ReadListener</code> and do dome dirty work inside. But I can't find the example of that Listeners. I believe it is not very easy.</p>
<p>Could you please provide example of servlet 3.1 feature in spring with explanation of Listener implementaion ?</p>

C++ beginner - trying to write a function but getting a identifier...is undefined : I am a student and am tasked with creating a program that will determine if a person is rich or not. My code is below and I keep getting an error that "identifier "isRich" is undefined. Can someone help me figure out where I went wrong? The instructions are:
We want to determine if someone is “rich.” The definition of being rich depends upon a number of factors such as age, number of dependents, amount of debt, etc., as well as other subjective factors.
Write a program that incorporates the use of functions:
In the main() function , display a pleasing banner of your choosing
From the main function, call a user-defined function calcWealth() which prompts the user for his age, amount of cash on hand, number of dependents, and amount of money owed to creditors. You should use an ‘int’ to represent age and number of dependents but use a ‘long’ to represent amount of cash on hand and amount owed.
Next, from the main() function, call a user-defined boolean function, isRich(), which accepts as arguments the age, cash on hand, number of dependents, and amount owed. isRich() will calculate the “true cash value” and then determine if someone is rich. Here are the criteria for isRich():
The amount owed must be subtracted from the cash on hand to determine a preliminary “true cash value”
If a person is has no dependents and a true cash value of $1 million or more, he can be considered rich – regardless of age.
If a person is < 40 years old, subtract $150,000 from his true cash value for each dependent (e.g., if a person has three dependents, subtract $450,000)
If a person is 40-50 years old, subtract $75,000 from his true cash value for each dependent
If a person > 50 years old, subtract $25,000 from his true cash value for each dependent
Return the value of ‘true’ to main() is the person’s true cash value >= $1 million; otherwise, return a value of ‘false’
The main() function receives the boolean value from isRich() and displays a message indicating whether a person is rich or not.
#include "stdafx.h"
#include <iostream> //for input and output
#include "Cusick Project 5.h"
using namespace std;
void calcWealth(int age, long cash, int dependants, long debt)
{
cout << "Please enter your age: ";
cin >> age;
cout << "Please enter the amount of cash on hand: ";
cin >> cash;
cout << "Please enter the amount of dependents you have: ";
cin >> dependants;
cout << "Please enter the amount of money you owe";
cin >> debt;
bool isRich(int *age, long *cash, int *dependants, long *debt);
{
long trueCash;
bool status = false;
trueCash = cash - debt;
if (dependants == 0)
{
if (trueCash >= 1000000)
{
status = true;
}
else
status = false;
}
else if (age < 40)
{
trueCash = trueCash - (dependants * 150000);
if (trueCash >= 1000000)
{
status = true;
}
else
status = false;
}
else if (age > 39 && age < 51)
{
trueCash = trueCash - (dependants * 75000);
if (trueCash >= 1000000)
{
status = true;
}
else
status = false;
}
else
{
trueCash = trueCash - (dependants * 25000);
if (trueCash >= 1000000)
{
status = true;
}
else
status = false;
}
}
}
int main()
{
int age;
long cash;
int dependants;
long debt;
bool status;
cout << "Welcome to the wealth indicator..." << endl;
calcWealth(age, cash, dependants, debt);
if (isRich(status) = true)
{
cout << "Congratulations! We consider you as being \"rich.\"" << endl;
}
else
{
cout << "I am sorry! You are not yet \"rich.\"" << endl;

How do I get the `hanami routes` command to include additional objects? : In the [overview documentation for routes][1] there are examples of objects being used for route resolution such as `get '/rack-app', to: RackApp.new` and it works as advertised with code like this:
`options '/*', to: MyApp::CORSRequestHandler.new`
From the console and the server commands, everything does what you would expect. However, when executing the command `hanami routes`, I get the following error:
`/path/to/gems/hanami-1.0.0/lib/hanami/config/mapper.rb:28:in `eval': uninitialized constant Hanami::Config::Mapper::MyApp (NameError)`
The problem is that the `routes` command is clearly not loading the entire app (which is good) but also problematic in this case. I had originally tried just using `require_relative` from `routes.rb` but since the file is eval'ed this fails miserably. (And, that just felt wrong.)
Being new to the framework I'm trying to figure how to best get this class definition included for the `routes` command in a way that's most consistent with Hanami itself.

How to configure ASP.NET Core 1.0 to use Local IIS instead of IIS Express? : <p>How can I setup a <strong>.Net Core 1.0</strong> project to use <strong>Local IIS</strong> instead of <strong>IIS Express</strong> when debugging?</p>
<p>I have tried modifying <strong>launchSettings.json</strong> file in various ways. For example, replacing all occurrences of <strong>IIS Express</strong> with <strong>Local IIS</strong> and updating the <strong>applicationUrl</strong> and <strong>launchUrl</strong> to use my custom localhost <a href="http://sample.local">http://sample.local</a> (I have updated the host file and configured IIS manager already) but not happy. </p>
<p>Default settings of <strong>Properties/launchSettings.json</strong> file:</p>
<pre><code>{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:38601/",
"sslPort": 0
}
},

keycloak bearer-only clients: why do they exist? : <p>I am trying to wrap my head around the concept of <code>bearer-only</code> clients in Keycloak.</p>
<p>I understand the concept of public vs confidential and the concept of service accounts and the <code>grant_type=client_credentials</code> stuff. But with <code>bearer-only</code>, I'm stuck.</p>
<p>Googling only reveals fragments of discussions saying:</p>
<blockquote>
<p>You cannot obtain a token from keycloak with a <code>bearer-only</code> client.</p>
</blockquote>
<p>The docs are unclear as well. All they say is:</p>
<blockquote>
<p>Bearer-only access type means that the application only allows bearer token requests.</p>
</blockquote>
<p>Ok, if my app only allows bearer token requests, how do I obtain this token if I cannot get it from Keycloak using client id / client secret?</p>
<p>And if you can't obtain a token, what can you at all? Why do these clients exist? Can somebody please provide an example of using this type of client? </p>

How to get the response of AJAX from JQUERY : <p>I know this question has been asked many times but the guys who asked before me had a slightly different issue. I have a [simple page to upload photo][1]. This one is placed on my localhost. I can select file and upload image into upload folder. I can get response and using Firefox console - "Net" tab - I can see the response - which is printed as html code. I could get the DOM using JQuery $("#message").html() function. However what I wanted to try is this. Instead of printing tags or JSON structure data just send error code. echo 0; for success. Echo -1; for failure. The live code is place [here][2]. Now what I tried with php file ajax_php_file.php is this:</p>
<pre><code><?php
if(isset($_FILES["file"]["type"]))
{
$validextensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES["file"]["name"]);
$file_extension = end($temporary);
if ((($_FILES["file"]["type"] == "image/png") ||
($_FILES["file"]["type"] == "image/jpg") ||
($_FILES["file"]["type"] == "image/jpeg")
) AND
$_FILES["file"]["size"] < 128000 AND // 125kb files can be uploaded.
in_array($file_extension, $validextensions)) {
if ($_FILES["file"]["error"] > 0)
echo '-1';
else
{
echo '-2';
if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo '-3';
}
else
{
$sourcePath = $_FILES['file']['tmp_name']; // Storing source path of the file in a variable
$targetPath = "upload/".$_FILES['file']['name']; // Target path where file is to be stored
move_uploaded_file($sourcePath,$targetPath) ; // Moving Uploaded file
echo '0';
}
}
}
else
{
echo '-3';
}

<p>So no html is send, just a 1 or two characters. When I check Firefox console on "Net" tab I see Just JSON but nothing more. So I have two questions here. Why I see no response, why I don't se the "0" when the file has been successfully uploaded? And then - how to fix the JS code to get the number or string without using any tags. Is this possible? My goal is to start functions which will print reports "File successly loaded" if the value is "0", or some error message if the value is less then 0.</p>

Duplicating (and modifying) discrete axis in ggplot2 : <p>I want to duplicate the left-side Y-axis on a ggplot2 plot onto the right side, and then change the tick labels for a discrete (categorical) axis.</p>
<p>I've read the answer to <a href="https://stackoverflow.com/questions/40134648/duplicating-discrete-axis-in-ggplot2">this question</a>, however as can be seen <a href="https://github.com/wilkelab/cowplot/blob/d10f9cad3123594e2925e680b8b2b59856c8833f/vignettes/axis_position.Rmd" rel="noreferrer">on the package's repo page</a>, the <code>switch_axis_position()</code> function has been removed from the <code>cowplot</code> package (the author cited (forthcoming?) native functionality in ggplot2).</p>
<p>I've seen the <a href="http://ggplot2.tidyverse.org/reference/sec_axis.html" rel="noreferrer">reference</a> page on secondary axes in ggplot2, however all the examples in that document use <code>scale_y_continuous</code> rather than <code>scale_y_discrete</code>. And, indeed, when I try to use the discrete function, I get the error:</p>
<pre><code>Error in discrete_scale(c("y", "ymin", "ymax", "yend"), "position_d", :
unused argument (sec.axis = <environment>)
</code></pre>
<p>Is there anyway to do this with ggplot2? Even a completely hacked solution will suffice for me. Thanks in advance. (MREs below)</p>
<pre><code>library(ggplot2)
# Working continuous plot with 2 axes
ggplot(mtcars, aes(cyl, mpg)) +
geom_point() +
scale_y_continuous(sec.axis = sec_axis(~.+10))
# Working discrete plot with 1 axis
ggplot(mtcars, aes(cyl, as.factor(mpg))) +
geom_point()
# Broken discrete plot with 2 axes

While loop inside While working just once in ruby? : <p>I am using while statement in ruby and another child while statement in that parent while to print :</p>
<pre><code>z = 0
i = 0
while z < 2
puts "hi coding"
while i < 4 do
puts "hello"
i +=1
end
z +=1
end
</code></pre>
<p>I want first ("hi coding") is printed and then ("hello,hello,hello,hello" four times) , and this total chunk printed twice but what is happening is that hi coding is printed twice and ( 4 times hello just once ):
so my output is like :</p>
<pre><code>hi coding
hello
hello
hello
hello
hi coding
*************************
</code></pre>
<p>but i want it as :</p>
<pre><code>hi coding
hello
hello
hello
hello
hi coding
hello
hello
hello
hello
*************************
</code></pre>
<p>what am I doing wrong here ?</p>

How to mock middleware in Express to skip authentication for unit test? : <p>I have the following in Express</p>
<pre><code> //index.js
var service = require('./subscription.service');
var auth = require('../auth/auth.service');
var router = express.Router();
router.post('/sync', auth.isAuthenticated, service.synchronise);
module.exports = router;
</code></pre>
<p>I want to override or mock isAuthenticated to return this</p>
<pre><code>auth.isAuthenticated = function(req, res, next) {
return next();
}
</code></pre>
<p>Here is my unit test:</p>
<pre><code>it('it should return a 200 response', function(done) {
//proxyquire here?
request(app).post('/subscriptions/sync')
.set('Authorization','Bearer '+ authToken)
.send({receipt: newSubscriptionReceipt })
.expect(200,done);
});
</code></pre>
<p>I have tried mocking index.js using proxyquire - I think I need to stub the router?
I have also tried to override in the test </p>
<pre><code>app.use('/subscriptions', require('./api/subscription'));
</code></pre>
<p>There must be a simple way to mock this out so I don't need to authenticate the request. Any ideas?</p>
