Check if test failed in afterEach of Jest

Here is an example how I solved it in my project: (Assuming that afterEach is used only for taking screenshots and not for cleanup and other navigates)

const testIt = (name, action) => {
    test(name, async () => {        
        try {         
            await action()} 
        catch (error) {           
            await screenshots.createScreenshot(page) //take screenshot 
            throw error
        }
    })
  }

describe('Test scenario 1', () => {
   
    testIt('test1 will Pass', async () => {
        expect(true).toBe(true)
    })
        
    testIt('test2 will Fail', async () => {
        expect(true).toBe(false)
    })

    afterEach(async () => {
        //ignored
    })

})

I use jest-html-reporters, and only failed tests will have attachment there (this solution did not require any other configurations). Result:

• test1 - passed, no screenshot
• test2 - failed, has screenshot

Seems the jasmine object can be used in Jest tests, but the currentSpec has been removed in the 2.x version.

I have found an alternative with the use of jasmine custom reports. Just make sure you also move the driver.quit() to the reporter as you might still need the driver after the test.

Here is an simple example for the reporter handling failing tests at the end of the test:

const reporter = {
  specDone: async (result) => {
    if (result.status === 'failed') {
      takeScreenshot(result.description);
    }
    await driver.quit();
  },
};

jasmine.getEnv().addReporter(reporter);

describe('Page', () => {  
  it('should contain Text in the header', async () => {
    // Arrange
    const page = new Page(driver);

    // Act
    await page.open();

    // Assert
    expect(await page.getHeaderText()).toBe('Something');
  });
});

Store current spec results in Jasmine and access it in afterEach.

@Niels van Reijmersdal is on the right track. However, the downside of taking a screenshot in specDone is that it runs after afterEach, so if there's something in afterEach that, say, navigates back a few screens, the screenshot you end up taking won't be representative of where the error took place. Here's an answer that allows you to take a screenshot immediately after the error occurs.

1. Add a custom Jasmine reporter for specStarted and store the spec results to jasmine.currentTest.

   jasmine.getEnv().addReporter( {
     specStarted: result => jasmine.currentTest = result
   } );
   

   The unintuitive thing about this is that even though we're storing this in specStarted before the results are in, jasmine.currentTest stores a reference to the result object which will get updated dynamically as the spec runs so when we access it in our afterEach, it will be holding the results of the spec properly.

2. Check for failedExpectations in your afterEach and take a screenshot if there's been any failures.

   afterEach( async () => {
     if ( jasmine.currentTest.failedExpectations.length > 0 ) { // There has been a failure.
       await driver.takeScreenshot();
     }
   } );
