testing

问题 This is the code I have written to perform a validation mechanism for comparing 2 files. I want to know is there a way to write it in a more performing way, because both of my files can have millions of records in it and this I believe will be slow in those cases. I am thinking of adding a Hash map, every time I get occurrence of a line in the file, I will add +1 to key value. If not, the value of the key remains 1. If the record exists in the other map of file 2 , then I remove it from first

问题 Is there a way to implement an AfterScenario hook to re-run the current test in case of Fail? Something like this: [AfterScenario("retry")] public void Retry() { if (ScenarioContext.Current.TestError != null) { // ? } } Note : The tests in my project are combined in Ordered tests and executed via MsTest . 回答1: The purpose of Specflow scenarios is to assert that a system is behaving as expected. If some temporal issue causes the test to fail, then getting the test to re-run and "hoping for the

问题 So I have a Directive that takes an input: @Directive({ selector: '[my-directive]' }) export class MyDirective { @Input('some-input') public someInput: string; } As you can see, the input should be a string value. Now, I want to write a test for this Directive, and I want to test if the input satisfies the string type: describe('MyDirective', () => { let fixture: ComponentFixture<DummyComponent>; let dummy: DummyComponent; let directive: DebugElement; beforeEach(async(() => { TestBed
