How to provide context of failed assertion in mocha.js?

@brandy 

To provide context of a failed assertion in Mocha.js, you can use the this.skip() function inside the test case to skip the test and provide a message explaining why the test was skipped. This can help provide more context about the failure when reviewing the test results.

Here is an example of how you can use this.skip() to provide context for a failed assertion in Mocha.js:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

describe('Example Test Suite', function() {
  
  it('should pass', function() {
    // Passing assertion
    assert.strictEqual(1 + 1, 2);
  });
  
  it('should fail with context', function() {
    const expected = 4;
    const actual = 2 + 2;
    
    if (actual !== expected) {
      this.skip('Test failed because the actual value is not equal to the expected value');
    }
  });
  
});

In this example, the test case 'should fail with context' will be skipped and a message will be logged explaining why the test was skipped when the actual value is not equal to the expected value. This can provide more context for the failure when reviewing the test results.
