asContextForEach

Provides a fresh value from this fixture as a context for each test declared in the content's scope.

Using this function implies a test-level fixture, whose value will be instantiated per test, and has a lifetime of that test. This is safe for concurrent test invocation, because values are isolated.

Note: As the context for tests in this scope is the fixture's value, the usual Test.ExecutionScope is unavailable as a context. Test.ExecutionScope is, however, provided as a parameter to each test.

Usage:

testFixture {
    object {
        var balance = 42.0
        fun add(value: Double) {
            balance += value
        }
    }
} asContextForEach {
    test("add 11.0") {
        add(11.0)
        assertEquals(53.0, balance)
    }
    test("add -11.0") {
        add(-11.0)
        assertEquals(31.0, balance)
    }
}
