Scripting tests Pro / Enterprise

For more advanced or custom assertions, you can use the kreya.test scripting function. This function is available in both Kreya operation scripts and Kreya scripts. These tests also run as part of a collection.

The kreya.test function accept a name and a boolean indicating whether the test was successful or a callback which can be used to run more complex assertions. Any callback returning false or throwing an error is considered a test failure. The popular Chai assertion library comes bundled with Kreya and allows complex assertions in the test callbacks.

Here are some examples:

Boolean assertions

// as simple boolean results
kreya.test('test that will fail', 2 >= 3);
kreya.test('test that will succeed', 6 === 6);

// or as callbacks
kreya.test('test that will fail', () => 2 >= 3);
kreya.test('test that will succeed', () => 6 === 6);

Chai assertions

import { expect } from 'chai'; // Chai is pre-installed in Kreya

kreya.test('test that will fail', () => expect(2).to.eql(3));
kreya.test('test that will succeed', () => expect(6).to.eql(6));

You can combine snapshot and scripting assertions in the same script:

import { expect } from 'chai';

kreya.snapshot.verifyObjectAsJson('response', responseData);

kreya.rest.onCallCompleted(ctx => {
  kreya.test('status code is 200', () => {
    expect(ctx.status.code).to.eql(200);
  });
});

While these examples are simple, you can create more realistic tests by referencing the gRPC or REST examples.
