[Feature Request] Opt-In to write Snapshots to other source roots

[Obirah]

I am using selfie to perform snapshot testing in Spring integration tests for Thymeleaf templates. In order to cleanly organize my test code, I have a separate (src/integrationTest/kotlin) source set for my integration tests that start a Spring test app.

When adding this source set to the otherSourceRoots value in SelfieSettings, selfie works nicely. However, (as intended and documented) selfie does not write Snapshot files to that source set but rather to src/test/kotlin.

I would love to see an option that allows to opt-in to writing the snapshots to the source set that the test is located in, so that other developers can easily find snapshots that I store and don't have to look for them in src/test.

You can override this method (@Override File getRootFolder() in java-speak) and set the snapshot folder to be whatever you want.

selfie/jvm/selfie-runner-junit5/src/main/kotlin/com/diffplug/selfie/junit5/SelfieSettingsAPI.kt

Lines 65 to 80 in a88b7a5

	/**
	* By default, the root folder is the first of the standard test directories. All snapshots are
	* stored within the root folder.
	*/
	open val rootFolder: File
	get() {
	val userDir = File(System.getProperty("user.dir"))
	for (standardDir in STANDARD_DIRS) {
	val candidate = userDir.resolve(standardDir)
	if (candidate.isDirectory) {
	return candidate
	}
	}
	throw AssertionError(
	"Could not find a standard test directory, 'user.dir' is equal to $userDir, looked in $STANDARD_DIRS")
	}

Is that enough control? Or do you want snapshots to be in multiple different source roots?

That's enough for me, thank you for pointing me towards that approach!
