The tests can describe xo methods or scenarios:

import xo from "../_xoConnection";

describe("user", () => {

  // testing a method
  describe(".set()", () => {
    it("sets an email", async () => {
      // some tests using xo methods and helpers from _xoConnection.js
      const id = await xo.createTempUser(SIMPLE_USER);
      expect(await xo.call("user.set", params)).toBe(true);
      expect(await xo.getUser(id)).toMatchSnapshot({
        id: expect.any(String),
      });
    });
  });
      
  // testing a scenario
  test("create two users, modify a user email to be the same with the other and fail trying to connect them", () => {
    /* some tests */
  });

});

Best practices

• The test environment must remain the same before and after each test:

  • each resource created must be deleted
  • existing resources should not be altered

• Make a sentence for the title of the test. It must be clear and consistent.

• If the feature you want to test is not implemented : write it and skip it, using it.skip().

• Take values ​​that cover the maximum of testing possibilities.

• If you make tests which keep track of large object, it is better to use snapshots.

• _xoConnection.js contains helpers to create temporary resources and to interface with XO.
  You can use it if you need to create resources which will be automatically deleted after the test:

  import xo from "../_xoConnection";
  
  describe(".create()", () => {
    it("creates a user without permission", async () => {
      // The user will be deleted automatically at the end of the test
      const userId = await xo.createTempUser({
        email: "wayne1@vates.fr",
        password: "batman1",
      });
      expect(await xo.getUser(userId)).toMatchSnapshot({
        id: expect.any(String),
      });
    });
  });

  The available helpers:

  • createTempUser(params)
  • getUser(id)
  • createTempJob(params)
  • createTempBackupNgJob(params)
  • createTempVm(params)
  • getSchedule(predicate)

Usage

• Before running the tests, you have to create a config file for xo-server-test.

  > cp sample.config.toml ~/.config/xo-server-test/config.toml
  

  And complete it.

• To run the tests:

  > npm ci
  > yarn test
  

  You get all the test suites passed (PASS) or failed (FAIL).

  > yarn test
  yarn run v1.9.4
  $ jest
   PASS  src/user/user.spec.js
   PASS  src/job/job.spec.js
   PASS  src/backupNg/backupNg.spec.js
  
  Test Suites: 3 passed, 3 total
  Tests:       2 skipped, 36 passed, 38 total
  Snapshots:   35 passed, 35 total
  Time:        7.257s, estimated 8s
  Ran all test suites.
  Done in 7.92s.
  

• You can run only tests related to changed files, and review the failed output by using: > yarn test --watch
