Protractor : How to run protractor script in different browsers

In our last post we have seen on how we can start our selenium standalone server using gulp. In order to perform cross browser testing it is needed to run our protractor script in different browser. Here we will see how we can do that by running our protractor script in different browser.

Protractor support four major browsers (Chrome, Firefox, IE and Safari).

If we use conf.js file to run our protractor script then we need to add Selenium capabilities object to our conf.js file.

Here capabilities is a json object to add browser name. Note that we have to change the browser name here to run our protractor script to our desired browser. If we use ‘chrome’ in place of ‘firefox’ then it starts running our script in chrome browser. Same for ‘safari’  and ‘internet explorer’. We can use two other keys with ‘version’ and ‘platform’.

Example : We use our previous project that we have developed in our previous post. Here we modify the conf.js file

Step 1 : Open the project and open conf.js file.

Step 2 : Add the following code for firefox browser. Note that chrome browser is by default for protractor. So we don’t need to mention it. If we implement firefox browser, we can add the following code in our conf.js file.

Now conf.js file looks like the following,

Step 3 : Now run the script by using the following command,

Note that we have to run Selenium standalone server before that.

When it starts running, opens the firefox browser and execute the steps.

If we want to run our scripts in multiple browsers at a time then we use multicapabilities object. For this we add the following code.

Now the conf.js file will be,

Now run the script. We see two browser window opens and execute the script. Note that we must have chrome and firefox installed on our machine.

In case of internet explorer, things are different.

Step 1 : Open the terminal and type the following to install IE driver

Step 2 : Add multicapabilities object to conf.js file like the following where browser name is ‘internet explorer’.

Step 3 : Run selenium standalone server.

Step 4 : Now run the script by using the following command,

We see IE browser window opens and execute the script.

In our next posts we will show how we can manage it other ways.

Protractor : How to start selenium server using gulp

In our previous post we see how we can run multiple javascript file. There we have started our selenium server by typing the following command at the terminal and pressing enter button. Every time we have to run it manually when executing our protractor script.

Gulp can handle the problem and it can run automatically when our protractor scripts start executing.

We have to add the following code in our gulpfile.js file.

Step 1 : At first add two variables like the following,

First one is for updating webdriver and second one is for starting Selenium server.

Step 2 : Now add this two task like the following,

Step 3 : Now modify default gulp.task() method.

Note that we have added two variables ‘webdriver_update’ and ‘webdriver_standalone’ as gulp.task() argument so that it runs first and then run the default task that means protractor script.

Step 4 : Now gulpfile.js file looks like the following,

Step 5 : Now run the protractor script using only gulp command and do not need to run selenium standalone server using manual command.

It first update selenium webdriver and then start the selenium standalone server. After that it starts executing protractor script.

That’s all from here. We will discuss more on gulp and protractor in future.

Protractor : How to run multiple protractor script Files using Gulp

In our last post we have discussed on running protractor script using gulp. In this post we will show how we can run multiple JavaScript files that contains protractor script.

For this purpose we will use our previous project that we have developed to implement gulp on protractor script.

Step 1 : Open the project using webstorm editor and add a new folder by right clicking on Project name and going to File>New>Directory

Step 2 : Enter the folder name as “test” and click Ok button.

Step 3 : Now move the test.js file to “test” folder by dragging the file and drop it to test folder. Move window is displayed and click OK button. Now test.js file is moved to test folder.

Step 4 : Rename the test.js file as testadd.js by right clicking on file name and going to Refactor>Rename.

Enter the file name “testadd.js” and click Refactor button.

Step 5 : Add another js file in the test folder by right clicking on folder and going to File>New>JavaScript File.

Step 6 : Enter file name as “testsub.js” and click on Ok button.

Step 7 : Open testsub.js file for subtraction and write the following code,

Note that above scripts subtract two numbers.

Step 8 : Now there are two files to run in the test folder. We can handle it by modifying gulpfile.js.

Step 9 : Open gulpfile.js and modify gulp.src() method by writing the following code,

Note that above expression means include all files as source files in the “test” folder that has .js extension. So it will execute all the .js extension files in the “test” folder.

Step 10 : Now gulpfile.js looks like the following,

 

Step 11 : Now go to terminal and start selenium server using the command,

Run the following command to run our protractor script.

gulp

Note that scripts run and at first it execute testadd.js file and then execute testsub.js files. It opened chrome browser and execute addition first and then subtraction. We get the following result.

That’s all from here. We will discuss more on gulp and protractor in future.

Protractor : How to automate AngularJS application using protractor

In my last post I have discussed about protractor and how to setup Protractor environment to run protractor test script. Here I will show you how to write protractor test script and run it using WebStorm editor.

Sample application : Note that we use Super calculator as sample AngularJS application. URL :http://juliemr.github.io/protractor-demo/

Test Cases : Verify that the application can add two numbers.

1. Open the application.
2. Enter First number.
3. Select operator (+,-,*…)
4. Enter Second number.
5. Click on Go button
6. Verify the result.

Step 1 : Create a Protractor Test project

• Open Webstorm IDE. Note that WebStorm can be downloaded from JetBrain’s site. You can use any other IDE to develop protractor scripts that supports JavaScript.
• Welcome to WebStorm window is displayed and click on “Create New Project” link.

• Select the project type as “Empty Project” and path. In my case path is “C:\Development\ProtractorTest”.

• Click on Create button.

• Right click on Folder name “ProtratorTest” Folder and click on JavaScript File.

• New JavaScript File window is displayed and enter the file name “test” and click on OK button.

• Now project is ready to write test script. test.js is the file to write test.

 

Step 2 : Write test script using JavaScript

• Write the following Script to open the application in test.js file.

Here describe and it comes from Jasmine framework. We will discuss it on future.

Common syntax of describe is,

describe(feature name, function(){

………

…….});

Common syntax for it is,

it(test case title, function(){

………….

….});

In order to write a test, syntax will be,

describe(feature name, function(){

      it(test case title, function(){…..

       …….

                 });

});

browser.get(url) is a protractor command to browse an application using a url given as argument.

• Now write the following code to enter first number.

Here element() is used to find an element and by.model() is a new locator in Protractor. Protractor uses some special locator to find out angularJS element beside selenium webdriver. We will discuss more on this in a separate post.

sendKeys() is a function to enter value/string to text box.

• Now select an operator. In this case it will be addition (+).

• Now write the following code to enter second number.

• Click on Go button.

• Verify the result.

Note that we use expect(……).toEqual(…) to verify the result.

Common syntax,

expect(actual value).toEqual(expected value);

• Now script of test.js file looks like the following,

 

Step 3 : Run Protractor Test

• Add a new JavaScript file named “conf.js” at the same directory. Note that conf.js is the file name only known by protractor at run time.

• Open conf.js file and write the following code.

Here, framework is the framework name. We use jasmine framework here.

seleniumAddress is the selenium server address running on the machine.

In my case  'http://127.0.0.1:4444/wd/hub'
We may write  'http://localhost:4444/wd/hub' is place of ip address.

specs is the JavaScript file name where scripts are written using protractor. In my case it is test.js.

• Now open a terminal window by clicking on Terminal tab.

• Terminal window look like this,

• At First we have to start our selenium server. Write the following command and press enter key.

• Selenium sever starts.

• Now open another terminal window by clicking (+) button

 

• Write the following command and press enter key.

• Scripts starts running and it opens the application and execute the steps.
• It shows the results in terminal window.

Note that we can use command prompt in place of Terminal window to run protractor script. Same command will be used and in that case we need to change the directory where test.js and conf.js file is located.

In our future post we will discuss more on protractor.
