VS2012 Creating unit Tests

Many people have a wrong understanding of unit tests. Think that unit testing is too time-consuming and affects progress. Actually do the project only to find that the code does not take a long time, but the bug is time-consuming. If we have a unit test, it will save us the development time from the first Test in place. There is a deeper meaning to unit testing. 1 It is a design 2 is a tool for project progress monitoring. 3 is also the best tool for learning open source projects.

Of course there are many tools for unit testing, so let's take a look at the unit test steps of VS2012.

The first step: Configure the environment for the test.

VS2010 can skip this step directly. Right-click on a class or method to see it directly. But the VS2012 need to be tuned out.

This step is a lot of online tutorials. Link is an article in the blog Park. Http://www.cnblogs.com/Gyoung/p/3143438.html

Step Two: Create a test project

Right-click the solution-add-new project-Test---test project.

Step three: Create a test class

The third step has two options.

First Kind

① Right-click the test Project-add unit tests. TestClass and TestMethod are the equivalent of tags in automatically created code.

② Add a reference. Add the required references to the previous layer.

For example, if you use layer three, you want to test the class and method of the D layer, then you should add all the references to the B layer.

③ write the contents of the test class. Take a simple example of what is called an assertion that involves a comparison of hypothetical values and results.

The above method is suitable for high-level people to write. But there is nothing really clear about the merits.

The second Kind

① find the class you want to test. Right--Create unit test--all the way.

The ② system will give an assertion that you can also fill out yourself. After all, many companies are testing the code coverage by certain requirements.

Fourth step: Verify your test.

Right-click on your test class and run the test. Wait a moment and the test results will appear.
