Normally, results are mapped as follows: * * pass: todo: Added to: Described as: Status: Expected: * true false passCount TEST-PASS PASS PASS * true true todoCount TEST-KNOWN-FAIL FAIL FAIL * false false failCount TEST-UNEXPECTED-FAIL FAIL PASS * false true failCount TEST-UNEXPECTED-PASS PASS FAIL * * The "allowFailure" argument indicates that this is one of the assertions that * should be allowed to fail, for example because "fail-if" is true for the * current test file in the manifest. In this case, results are mapped this way: * * pass: todo: Added to: Described as: Status: Expected: * true false passCount TEST-PASS PASS PASS * true true todoCount TEST-KNOWN-FAIL FAIL FAIL * false false todoCount TEST-KNOWN-FAIL FAIL FAIL * false true todoCount TEST-KNOWN-FAIL FAIL FAIL */ function testResult({ name, pass, todo, ex, stack, allowFailure }) { this.info = false; this.name = name; this.msg = ""; if (allowFailure && !pass) { this.allowedFailure = true; this.pass = true; this.todo = true; } else { this.pass = !!pass; this.todo = todo; } this.expected = this.todo ?
