unit-testing

Ruby on rails generates tests for you. Do those give a false sense of a safety net?

Disclaimer: I have not used RoR, and I have not generated tests. But, I will still dare to post this question. Quality Assurance is theoretically impossible to get 100% right in general (Undecidable problem ;), and it is hard in practice. So many developers do not understand that writing good automated tests is an art, and it is hard. ...

Testing system where App-level and Request-level IoC containers exist

My team is in the process of developing a system where we're using Unity as our IoC container; and to provide NHibernate ISessions (Units of work) over each HTTP Request, we're using Unity's ChildContainer feature to create a child container for each request, and sticking the ISession in there. We arrived at this approach after trying o...

testing Clojure in Maven

I am new at Maven and even newer at Clojure. As an exercise to learn the language, I am writing a spider solitaire player program.

Unit Test json output in Zend Framework

The Zend Tutorial lists many assertions to check the output generated by a request. http://framework.zend.com/manual/en/zend.test.phpunit.html But they all seem to assume that the output is html. I need to test json output instead. Are there any assertions helpful to check json, or is there at least a generic way to make assertions ag...

How to unit test internals (organization) of a data structure?

I've started working on a little ruby project that will have sample implementations of a number of different data structures and algorithms. Right now it's just for me to refresh on stuff I haven't done for a while, but I'm hoping to have it set up kind of like Ruby Koans, with a bunch of unit tests written for the data structures but t...

Unit test project doesn't recognize the classes it was generated from

I have a fairly simple file-system website consisting of one aspx page and several classes in separate .cs files. Everything is on my own HD. The web app itself builds and runs fine. Out of curiosity I decided to try out Visual Studio's nifty, easy-to-use unit test feature. So I opened each class file and clicked Create Unit Tests. VS ge...

Unittest in Django. Static variable feeded into the test case

I want to generate some dynamic data and feed these data in to test cases. But I found that Django will initial the test class every time to do the test. So the data will get generated every time django test framework calls the function. Is there anyway to use something like the singleton or static variable to solve the problem? What s...

Why are my rails tests so slow?

Is it normal for my test suite to take 5 seconds just to launch? Even when running an empty suite it still takes this long. Is it because it's firing up a new instance of rails on each run? If so, is there anyway to keep it persistent? Example: rlepidi@rlepidi:~/projects/rails/my_project$ time rake test /usr/bin/ruby1.9.1 -I"lib:test" ...

Django TestCase testing order

If there are several methods in the test class, I found that the order to execute is alphabetical. But I want to customize the order of execution. How to define the execution order? For example: testTestA will be loaded first than testTestB. class Test(TestCase): def setUp(self): ... def testTestB(self): #test ...

Problem testing a plugin with 2 diff versions of rails installed on the system

Hi, I have some unit tests for a plugin I have written. This plugin is attached to a sample rails application. Both the rails application and the plugin is configured for rails 2.2.2. So far my system had ruby 1.8.7 with rails 2.2.2 and I faced NO issues running the unit tests in my plugin or the tests of my sample rails app. Just a c...

Tests that are 2-3 times bigger than the testable code

Is it normal to have tests that are way bigger than the actual code being tested? For every line of code I am testing I usually have 2-3 lines in the unit test. Which ultimately leads to tons of time being spent just typing the tests in (mock, mock and mock more). Where are the time savings? Do you ever avoid tests for code that is alo...

Asp.Net MVC Tutorial Unit Tests

I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors. In the example below it tests the CheckOut ViewResult: [AcceptVerbs(HttpVerbs.Post)] public ViewResult CheckOut(Cart cart, FormCollection form) { // Empty carts can't be checked out i...

How can I specifiy JUnit test dependencies?

Our toolkit has over 15000 JUnit tests, and many tests are known to fail if some other test fails. For example, if the method X.foo() uses functionality from Y.bar() and YTest.testBar() fails, then XTest.testFoo() will fail too. Obviously, XTest.testFoo() can also fail because of problems specific to X.foo(). While this is fine and I st...
