describe( name, function )

describe is a wrapper of group that adds the ability to:

  • Catch exceptions to allow continuing the execution outside of the describe function.
  • Returns a boolean to indicate the success of all its k6chaijs assertions.
JavaScript
JavaScript 
import { describe, expect } from 'https://jslib.k6.io/k6chaijs/4.3.4.3/index.js';

export default function testSuite() {
  const success1 = describe('Basic test', () => {
    expect(1, 'number one').to.equal(1);
  });
  console.log(success1); // true

  const success2 = describe('Another test', () => {
    throw 'Something entirely unexpected happened';
  });
  console.log(success2); // false

  const success3 = describe('Yet another test', () => {
    expect(false, 'my vaule').to.be.true();
  });
  console.log(success3); // false
}

Chaining describe() blocks

If you want to skip the execution of the following describe blocks, consider chaining them using && as shown below.

JavaScript 
import { describe, expect } from 'https://jslib.k6.io/k6chaijs/4.3.4.3/index.js';

export default function testSuite() {
  describe('Basic test', () => {
    expect(1, 'number one').to.equal(1);
  }) &&
    describe('Another test', () => {
      throw 'Something entirely unexpected happened';
    }) &&
    describe('Yet another test', () => {
      // the will not be executed because the prior block returned `false`
      expect(false, 'my vaule').to.be.true();
    });
}
