NativeScript tests fail to run - nativescript

Question

The tests appear to run in the simulator because an app launches briefly with text that says "Testing in Progress" then "Total: 0, Passed: 0, Failed: 0" (took a video of the simulator window).
This is a NativeScript Angular project using TypeScript. I have tried an example as both src/app/tests/example.js and src/app/tests/example.ts with the following:
// A sample Jasmine test
describe('A suite', () => {
it('contains spec with an expectation', () => {
expect(true).toBe(true);
});
});
Last few lines of log after running tns test ios.

Answer 1

I had the tests in the wrong folder. Tried src/tests and src/app/tests. Noticed app/tests was mentioned but thought it meant src/app.
N.B. tns test init did not create any files in app/tests.
