// A minimal async test runner for Qt async auto tests.
//
// Usage: Call runTest(name, testFunctionCompleted), where "name" is the name of the app
// (the .wasm file name), and testFunctionCompleted is a test-function-complete
// callback. The test runner will then instantiate the app and run tests.
//
// The test runner expects that the app instance defines the following
// functions:
//
// void cleanupTestCase()
// string getTestFunctions()
// runTestFunction(string)
//
// Further, the test runner expects that the app instance calls
// completeTestFunction() (below - note that both the instance and this
// file have a function with that name) when a test function finishes. This
// can be done during runTestFunction(), or after it has returned (this
// is the part which enables async testing). Test functions which fail
// to call completeTestFunction() will time out after 2000ms.
//
