Tutorial​​ 20​​ ​​ ​​ ​​ Integrate​​ Cucumber​​ with​​ Selenium​​ – Part​​ 7

What you will Learn :

  • Create​​ Runner file

  • Execute Runner file

  • One important note

  • Cucumber report

  • Introduce an error to generate a screenshot

  • Exercise

This is continuation of previous tutorial.

Create​​ Runner file​​ 

Let us create MyRunnerTest.java inside the TestRunner package. Make sure that the name of the file has a suffix ‘Test’​​ otherwise there would be problems in execution (we have already studied this​​ in​​ one of​​ our previous tutorial)

Like studied earlier, we will add​​ cucumber options as seen below​​ 

Execute Runner file

The 3 scenarios in our feature file get executed one by one

Let us now execute our runner file

Notice below that the execution starts and JUnit console points to execution of our first scenario​​ 

The browser opens and launches website. The login page title is verified using assertion

Below points towards execution of 2nd​​ scenario

Browser​​ gets launched and ‘Forgot password link’ gets asserted​​ 

Below points towards execution of 3rd scenario

The username/password is entered and scropt clicks the ‘Sign In’ button. The home page title is asserted

Below shows that all the 3 scenarios were executed successfully

Below is complete console o/p

Why is it that a new chrome browser session starts before starting every scenario? This is because of the @Before methods that we have written in ApplicationHooks file

One important note

There is one more point worth mentioning over here. Look at​​ steps number 5 and 6 in​​ our feature file below.​​ These steps start with ‘When’ and ‘Then’.​​ 

As expected, our step definition file (right hand side) too starts with ‘@When’ and ‘@Then’ respectively for the steps number 5 and 6​​ in our feature file.

But the notable point to note here is that, the steps number 17 and 18 in our feature file do NOT start with ‘When’ and ‘Then’. These start with ‘Then’ and ‘And’. We do NOT have corresponding @Then and @And in our step definition file. Then how come these steps (17 and 18) are getting executed at runtime? Why are we not seeing any error at runtime saying that “could​​ not find any step definition for these 2 steps…”​​ ?

To answer this question, what matters is the regular expression inside the annotations of step definition file. So if you look at below, the regex "user gets the title of the page" and "page title should be {string}"​​ in step definition file match with the description of steps in the feature file. So that is what matters

Cucumber report

Let us copy the cucumber report link seen in console

Paste the link in a browser, observe that all the scenarios are Pass​​ 

Introduce an error to generate a screenshot

In our hooks file (see below), we have @After hook that would take a screenshot if the test fails​​ 



So to test this, let us introduce an error in forgotPwdLink locator, let us add 123 as seen below.​​ 

So this would fail​​ isForgotpwdLinkPresent() action

Let us re-run our runner file and copy the cucumber report link from console​​ 

Paste it in browser. Notice that the below scenario fails and an image is attached

Let us click ‘Attached image’, notice below the screenshot. Hence @After hook that takes a screenshot if the test fails is working fine​​ 

You can delete the report

Exercise

As an exercise, execute the scenarios in firefox browser.

This ends​​ our​​ core Cucumber​​ BDD series.​​
