Using Firebase Test Lab for Testing test cases of Phimpme Android

As now we started writing some test cases for Phimpme Android. While running my instrumentation test case, I saw a tab of Cloud Testing in Android Studio. This is for Firebase Test Lab. Firebase Test Lab provides cloud-based infrastructure for testing Android apps. Everyone doesn’t have every devices of all the android versions. But testing on all of them is equally important.

How I used test lab in Phimpme

  • Run your first test on Firebase

Select Test Lab in your project on the left nav on the Firebase console, and then click Run a Robo test. The Robo test automatically explores your app on wide array of devices to find defects and report any crashes that occur. It doesn’t require you to write test cases. All you need is the app’s APK. Nothing else is needed to use Robo test.

Upload your Application’s APK (app-debug-unaligned.apk) in the next screen and click Continue

Configure the device selection, a wide range of devices and all API levels are present there. You can save the template for future use.

Click on start test to start testing. It will start the tests and show the real time progress as well.

  • Using Firebase Test Lab from Android Studio

It required Android Studio 2.0+. You needs to edit the configuration of Android Instrumentation test.

Select the Firebase Test Lab Device Matrix under the Target. You can configure Matrix, matrix is actually on what virtual and physical devices do you want to run your test. See the below screenshot for details.

Note: You need to enable the firebase in your project

So using test lab on firebase we can easily test the test cases on multiple devices and make our app more scalable.

Getting fired up with Firebase Database

As you might’ve noticed, in my Open Event Android Project, we are asking the user to enter his/her details and then using these details at the backend for generating the app according to his/her needs.

One thing to wonder is how did we transmit the details from webpage to the server.

Well, this is where Firebase comes to the rescue one more time!

If you’ve read my previous post on Firebase Storage, you might have started to appreciate what an awesometastic service Firebase is.

So without any further adieu, lets get started with this.

Step 1 :

Add your project to Firebase from the console.

 newProj
Click on the Blue button

Step 2 :

Add Firebase to your webapp

Open the project, you’ve just created and click on the bright red button that says, “ Add Firebase to your web app”

 addFirebase

Copy the contents from here and paste it after your HTML code.

Step 3 :

Next up, navigate to the Database section in your console and move to the Rules tab.

For now, let us edit the rules to allow anyone to read and write to the database.

 screenshot-area-2016-07-18-204437

Almost all set up now.

Step 4 :

Modify the HTML to allow entering data by the user

This looks something like this :

<form name="htmlform" id="form" enctype="multipart/form-data">
<p align="center"><b><big>FOSSASIA's App Generator</big></b></p>
<table align="center"
width = "900px"
height="200px">
<tr>
<td valign="top">
<label for="Email">Email</label>
</td>
<td valign="top">
<input id="email" type="email" name="Email" size="30">
</td>
<td>
<td valign="top">
<label for="name">App's Name</label>
</td>&nbsp;
<td valign="top">
<input id="appName" type="text" name="App_Name" maxlength="50" size="30">
</td>&nbsp;
</tr>
<tr>
<td valign="top">
<label for="link">Api Link</label>
</td>
<td valign="top">
<input id="apiLink" type="url" name="Api_Link" maxlength="90" size="30">
</td>
</tr>
<tr>
<td valign="top">
<label for="sessions">Zip containing .json files</label>
</td>
<td valign="top">
<input accept=".zip" type="file" id="uploadZip" name="sessions">
</td>
</tr>
<tr>
<td colspan="5" style="text-align:center">
<button type="submit">Generate and Download app</button>
</td>
</tr>
</table>
</form>

Now let us setup our javascript to extract this data and store this in Firebase Database.

<script src="https://www.gstatic.com/firebasejs/live/3.0/firebase.js"></script>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script src="https://code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<script>
var $ = jQuery;
var timestamp = Number(new Date()); //this will server as a unique ID for each user
var form = document.querySelector("form");
var config = {
apiKey: "API_KEY",
authDomain: "app-id.firebaseapp.com",
databaseURL: "https://app-id.firebaseio.com",
storageBucket: "app-id.appspot.com",
};
firebase.initializeApp(config);
var database = firebase.database();
form.addEventListener("submit", function(event) {
event.preventDefault();
var ary = $(form).serializeArray();
var obj = {};
for (var a = 0; a < ary.length; a++) obj[ary[a].name] = ary[a].value;
console.log("JSON",obj);
var file_data = $('#uploadZip').prop('files')[0];
var storageRef = firebase.storage().ref(timestamp.toString());
storageRef.put(file_data);
var form_data = new FormData();
form_data.append('file', file_data);
firebase.database().ref('users/' + timestamp).set(obj);
database.ref('users/' + timestamp).once('value').then(function(snapshot) {
console.log("Received value",snapshot.val());
)};
});
</script>

We are almost finished with uploading the data to the database.

Enter data inside the fields and press submit.

If everything went well, you will be able to see the newly entered data inside your database.

screenshot-area-2016-07-18-205651.png

Now on to retrieving this data on the server.

Our backend runs on a python script, so we have a library known as python-firebase which helps us easily fetch the data stored in the Firebase database.

The code for it goes like this

firebase = firebase.FirebaseApplication('https://app-id.firebaseio.com', None)
result = firebase.get('/users', str(arg))
jsonData = json.dumps(result)
email = json.dumps(result['Email'])
email = email.replace('"', '')
app_name = json.dumps(result['App_Name'])
app_name = app_name.replace('"', '')
print app_name
print email

The data will be returned in JSON format, so you can manipulate and store it as you wish.

Well, that’s it!

You now know how to store and retrieve data to and from Firebase.
It makes the work a lot simpler as there is no Database schema or tables that need to be defined, firebase handles this on its own.

I hope that you found this tutorial helpful, and if you have any doubts regarding this feel free to comment down below, I would love to help you out.

Cheers.

Set up Firebase to upload user files

If you’ve read my previous post on uploading files to server, you might have noticed that it was not an easy task to achieve.

There is way too much boilerplate code for uploading a single file, and it will be much more complex in case we plan to upload multiple files, which I need to do for my project.

So what’s the solution to this?

ENTER FIREBASE!

Yeah, you read it right, Firebase once again to the rescue!

I came to know that firebase allows user to store and access the files easily to the built in storage.

Enough chatter for now, lets get to code!

Step 1 :

Add your project to Firebase from the console.

newProj.PNG

Click on the Blue button

Step 2 :

Add Firebase to your webapp

Open the project, you’ve just created and click on the bright red button that says, “ Add Firebase to your web app”

addFirebase.PNGCopy the contents from here and paste it after your HTML code.

Step 3 :

Open the “Storage” tab from the navigation drawer and navigate to the rules tab over there.
We need to set up specific rules as to who all can upload and read files to the storage bucket.

storageRules.PNG
For testing purposes, I’ve allowed everyone to read and write to my storage, but that shouldn’t be the case for your production app

Step 4 :

Add code for uploading your files.

First create a document selection widget and an upload button in your website’s index.html.

<tr>
<td valign=”top”>
<label for=”icon”>Zip File</label>
</td>
<td valign=”top”>
<input accept=”.zip” type=”file” id=”uploadZip” name=”icon”>
</td>
</tr>

Next, create a button to initiate the upload

<tr>
<td colspan=”5″ style=”text-align:center”>
<button type=”submit”>Upload Zip</button>
</td>
</tr>

Next up, inside the JavaScript, add a submitlistener for the submit button and call preventDefault inside it to prevent the form from doing the default action.

var form = document.querySelector(“form”);
form.addEventListener(“submit”, function(event) {
event.preventDefault();

Next up, get a reference to the upload location from your firebase storage bucket.

var timestamp = Number(new Date());
var storageRef = firebase.storage().ref(timestamp.toString());

Next, get the upload button from its ID and add its contents to a variable named file_data.

var $ = jQuery;
var file_data = $(‘#uploadZip’).prop(‘files’)[0];

Now upload that file to firebase.

storageRef.put(file_data);

If everything went as expected, you’ll be able to see the uploaded files onto your firebase console.

 storage

So, you can really appreciate the awesomeness of Firebase by now.
It has replaced the work done by over 50+ lines of code (spread around AJAX calls, PHP Scripts and JavaScript methods) by a single method call.

I would urge you to go through the documentation for more clarity on this.
https://firebase.google.com/docs/storage/

Well, that was it for now.
Next time, I’ll tell you how to retrieve the files back from the storage and add user’s details to Firebase Database.(Yeah, no need for Tables and SQL anymore!)

Cheers. 😀
