Need to create project directory explicitly before each unit test

I'm using light unit tests with default fixture:

class ProjectTest : BasePlatformTestCase() {

    var file: String? = null

    @BeforeEach
    fun setup() {
        super.setUp()
        file = "${project.basePath}/${UUID.randomUUID()}.tmp"
        Files.createDirectories(Path.of(project.basePath)) <-- without this second test fails because of missing directory
    }

    @AfterEach
    fun teardown() {
        super.tearDown()
    }

    @Test
    fun test1() {
        assertTrue(createFile()?.exists() == true)
    }

    @Test
    fun test2() {
        assertTrue(createFile()?.exists() == true)
    }

    private fun createFile(): VirtualFile? {
        val tempFile = File("${project.basePath}/${UUID.randomUUID()}.tmp")
        tempFile.createNewFile() <-- fails here 2nd time because parent dir does not exist
        tempFile.deleteOnExit()
        return VfsUtil.findFileByIoFile(tempFile, true)
    }

}

Seems like project directory is removed on tearDown but it is not created on setUp.

Please point me to right direction if above is wrong.

Use the provided CodeInsightTestFixture from field myFixture to create files/directories in the current test project instance.

Thank for hint, but above creates file in `temp://` which is not reachable in my project because I'm using findFileByIoFile due to processing file by io paths.

Why do you use regular java.io.File instead of VirtualFile if they're located inside the project AFAIU?

Otherwise, you can employ some hack to distinguish test mode filesystem

final VirtualFile relativeFile = ApplicationManager.getApplication().isUnitTestMode() ?
                                 TempFileSystem.getInstance().findFileByPath(path) :
                                 <IO File Lookup>;
