Any way to make screenshot when soft assertion failed?

[borzykin]

So as simple as that, can't figure out how to take screenshot at the moment of soft assert failure instead of at the end of test, Using testNg btw

@borzykin not sure how much help this will be, but you could potentially use a custom soft assertion provider that just delegates to the default provider implementation.

In this provider, you may be able to try-catch any AssertionError and use java.awt.Robot to capture the primary display device to a BufferedImage.

I have not used TestNG but you may be able to find a way to infer the test name (maybe by walking the stack trace of the thread), to get a meaningful file name for the image to save.

If you didn't need it for the specific assertion, but just the final assertion error that is thrown, you could just have a lambda that wraps your test case and catches an AssertionError, takes the screenshot using robot, and then rethrows the error again.

There are two options:

• Call setAfterAssertionErrorCollected on your SoftAssertions instance, providing your own AfterAssertionErrorCollected implementation (can be a lambda).
• Extend AbstractSoftAssertions and overrride onAssertionErrorCollected​.

Both ways allow you to provide your own logic to be executed with each assertion error.

You can find examples about both solutions in the AssertJ documentation.
