![]() If any other code in my test method throws that exception (or if my code throws any other kind of exception), my test will be flagged as failed. This test will now pass if (and only if) this call to the GetCustomer method throws a NullReferenceException. This example checks to see if the GetCustomer method throws a NullReferenceException when the GetCustomer method is called with an empty string:Īssert.ThrowsException(() => cust = CustomerRepository.GetCustomer("")) ![]() With either of those methods, you specify the exception you expect to get from your method and then pass the code you want to test (as a lambda expression) to the method. You have a better alternatives: the Assert object's ThrowsException and ThrowsExceptionAsync methods. That's not quite what you want to test for. In more complex projects, you may have more than one jsconfig.json file defined inside a. let title 'Hr kommer valda ltar synas', targ document.querySelector ('oneSong'), items document.querySelectorAll. Main problem is that it isn't working at all on my IDE. Which it does (on stackoverflow) for the first row of boxes but then stops. A JavaScript project is the source files of the project and should not include the derived or packaged files (such as a dist directory). Basically what I want is when you check in a box the music and price should be added. Unfortunately, that exception may or may not have been thrown where you actually expected it to be thrown. To define our code as a JavaScript project, create jsconfig.json at the root of your JavaScript code as shown below. The problem with ExpectedException is that it applies to the whole test method, not just the "code under test." This means that if your test or production code throws that exception anywhere at all, the ExpectedException attribute will tell you that your test has passed. ![]() But that doesn't mean that I think Visual Studio Test is perfect.įor example, the ExpectedException attribute, when placed on a test method, lets you check to make sure that your code throws the appropriate exception when something goes horribly wrong. I've always argued that the only easier way to test your code than using Visual Studio Test is to not test at all. ![]()
