问题
I want to know what exact software should I install before I run my automation project. Selenium web driver, selenium java, testNG, junit was installed but there are some problems with that also. 1. Selenium java file doesn't have more JAR files like people shows in their video tutorials. 2. When I' going to run my project as testNG, eclipse said windows firewall has blocked some features of this app.
回答1:
This error message...
[TestNG] No tests found. Nothing was run
...implies that TestNG didn't find any @Test to execute.
Your main issue is though you have imported Test as:
import org.testng.annotations.Test;
But your code block has no @Test as such but includes a @BeforeClass. As there are no tests, TestNG doesn't find any Test to execute.
Solution
The easiest solution would be to change the @BeforeTest annotation with @Test and execute you Test case / Test Suite.

Because your main method have been put under beforeclass annotation. The main method does not take any annotation. If you provide any TestNG annotation to the main method then this error is thrown. When using TestNG you don't write a main method. It is not that main method along with other tests with @test annotation will not run, it is just that the main method does not take any annotation. It is only the non-main methods that take TestNG annotations. If you have a regular java main method and the other @test methods in the same class, the program will compile and run successfully but the main method will be ignored and won't run at all. It is only the other @test methods that will run.
