TTK - Enable native javascript test framework for test case execution

[vijayg10]

Goal:

As a Mojaloop implementer

I want to write my test cases in a stadard javascript test frame work like Jest instead of TTK's own format

so that I can use my own tools like editors and libraries in test cases

Acceptance Criteria:

• [ ] TTK tests can be written in a standard javascript test framework

Complexity: Low

Uncertainty: Medium (Design decisions may vary based on the feedback from reviewers)

---

Tasks: TBD

Done

• [ ] Acceptance Criteria pass
• [ ] Designs are up-to date

Pull Requests:

• [ ] TBD

Follow-up:

• N/A

Dependencies:

As per Matt's update the following code converts JS test to TTK test. https://github.com/msk-/ml-testing-toolkit/blob/feature/support-javascript-tests/src/lib/parseJsTest.js Some comments from Matt. It's not overly intelligent, but it does basically parse and analyse the structure of the js test to transform it to the TTK data format. Some notes

• it needs tidying up
• it doesn't yet handle test framework infrastructure such as beforeEach, beforeAll etc.- this might not be possible without an extension to the data format
• it needs more testing!
• it needs a TTK data format -> JS test converter, but that shouldn't be such a big deal

The code converts the following code

const syncClient = require('sync-client')
describe('Server', () => {
  it('starts', () => {
    const fspiopRequest = {
      operationPath: 'whatever',
      method: 'get',
      headers: {},
      params: {},
      apiVersion: {
        minorVersion: 1,
        majorVersion: 0,
        type: 'fspiop',
        asynchronous: false,
      },
      url: 'whatever',
    }
    const resp1 = syncClient(fspiopRequest)
    console.log('this log statement is post-request script 1')
    expect(resp1).whatever()
    const fspiopRequest2 = {
      operationPath: 'whatever',
      method: 'get',
      headers: {},
      params: {},
      apiVersion: {
        minorVersion: 1,
        majorVersion: 1,
        type: 'fspiop',
        asynchronous: false,
      },
      url: 'whatever',
    }
    const resp2 = syncClient(fspiopRequest2)
    console.log('this log statement is post-request script 2')
    expect(resp2).whatever()
    expect(resp2).whatever()
  })
})
