I am in the process of transferring a large number of JUnit tests to test TypeScript code on Node.js. While I understand that annotations are still an experimental feature in TypeScript/JavaScript, my goal is to utilize the familiar @Before, @Test, and @After source annotations similar to those in JUnit.
Additionally, having the output in the same JUnit XML format would be highly beneficial.
Although I may be a bit late in responding, I suggest taking a look at TestyTs
This library provides support for annotations similar to those found in JUnit:
@TestSuite()
export class MyTestSuite {
@BeforeEach()
beforeEach() {
// Perform an action
}
@Test()
onePlusOne() {
const result = 1 + 1;
expect.toBeEqual(result, 2);
}
@AfterEach()
afterEach() {
// Perform an action
}
}
You can test it out on REPL
It would be optimal if it utilized the same @Before, @Test, and @After source annotations that JUnit does.
Currently, none of the popular JavaScript frameworks incorporate these annotations. Mocha is currently leading the pack in terms of test frameworks, as evidenced by npm download statistics:
Notably, Mocha is the preferred test framework used by the TypeScript team: https://github.com/Microsoft/TypeScript/blob/d1ac8dde0b2a9bc4929cc45a918e29dda651dafe/package.json#L69
This is why I also endorse Mocha in my alm project: https://basarat.gitbooks.io/alm/content/features/testing.html
