Test Drive / tesg

A very simple test runner, inspired by Jest and articles related to it and it's inner workings.

Min Requirements

NodeJS > 14.0.0

Get Started

npm i -g tesg

Run Tests

tesg <directory/filename>

In case of a directory, the files to be tested should have .test in their name.

Examples of Tests

// ✅ Valid
describe("Suite 1", () => {
	test("Test Case 1", () => {
		expect(1 === 2).toBe(false);
	});
});

describe("Suite 2", () => {
	test("Test Case 2", () => {
		expect(1 === 2).toEqual(false);
	});

	test("Test Case 3", () => {
		expect(1 == true).toEqual(true);
	});
});

// ❌ Invalid
describe("Suite 3", () => {
    // No test cases. Will throw an error.
})

test("Test case 4", () => ...); // Cannot put it/test functions outside a 'describe' block.

expect(1 === 1).toBe(true); // Cannot put an expect block outside of a 'test/it' block.

Available Assertions

• toBe
• notToBe
• toNotBe
• toEqual
• toHaveBeenCalledTimes - In case of mocked functions

Limitations

Assertions don't work on Objects yet, will add support for it later.

Async operations are not supported yet.
