Feature/temp dir cleanup #2729

ghost · 2021-09-26T13:34:11Z

Overview

Addressing issue #2159 .

This PR adds a TempDirStrategy annotation for managing TempDirs. The annotation has a single CleanupMode enum field that can have a value of ALWAYS or NEVER. If the field is NEVER, then a test class's TempDirs are not cleaned up after the test completes. The annotation also works on nested classes, and a config parameter for the default cleanup mode has been added. Unit tests, demo and documentation included.

The issue discussion included the idea of an 'on_success' mode, but I have been unable to work out how to achieve this. Happy to discuss ideas on how this might be done.

@hglasgow Sorry for the wait!

The issue discussion included the idea of an 'on_success' mode, but I have been unable to work out how to achieve this. Happy to discuss ideas on how this might be done.

I think we should be able to pass the ExtensionContext to CloseablePath when it's created and check if ExtensionContext.getExecutionException is empty or contains an instance of TestAbortedException.

…ngineTests.

All done, ready for review.

Thanks! I found one additional minor thing.

+		@AfterAll
+		static void afterAll() {
+			if (defaultParameterDir != null && defaultParameterDir.exists()) {
+				defaultParameterDir.delete();


File.delete returns a false if the file wasn't deleted for some reason. Instead, I think we should use Files.deleteIfExists (and Path in the test cases) which only returns false if the file didn't exists and throws an exception if there was a problem deleting it.

Okay, that's done.
