Listener: add text to error text?

[MCMic]

Hello,

I wanted to create a modified version of PHPUnit_Extensions_Selenium2TestCase_ScreenshotListener to add a link to the screenshot in the error text.
But I can’t find any way to alter output using a Listener, it seems printf just outputs to the terminal, and I’m not sure if a listeners methods can return something and how it should be formatted?
How can a Listener add some text to the test result?

[sebastianbergmann]

Listeners are for listening. They should not modify anything.

Then how can I add a link to the screenshot in the error text?

I do not know anything about PHPUnit_Extensions_Selenium2TestCase_ScreenshotListener so I cannot help you. Please bring this up with the vendor of your PHPUnit extension.

This is a more general question about how to add information to tests results.
This listener create a screenshot on failure which is quite useful but I have to search for which file match which failed test myself. It would be useful if I could expand the failed test text so that it contains the filename (which is generated from easily available information like test name and such things).

A listener is a listener. It must only listen. If it does something more then that is wrong.

It is a mistake in the implementation of PHPUnit that listeners can manipulate PHPUnit\Framework\Test object. I should have fixed this mistake a long time ago. I plan to correct this for PHPUnit 7 (see #2477).

You already said this, my question is what can I do to alter the test result text. I won’t use a Listener if it can’t do it, is there an other way mechanism capable of altering the text output?
