Pattern: Chai call with vague failure message
Issue: -
Avoid Chai assertions that result in vague errors. For example,
asserting expect(something).to.be.true will result in the failure
message "Expected true received false". This is a vague error message
that does not reveal the underlying problem. It is especially vague in
TypeScript because stack trace line numbers often do not match the
source code. A better pattern to follow is the xUnit Patterns Assertion
Message pattern. The previous code sample could be better written as
expect(something).to.equal(true, 'expected something to have occurred');
