为每个测试用例打开一个新的浏览器是一种好习惯吗？ （硒，JUnit）

Question

I am using Selenium and JUnit for testing. First time doing testing, so I'm not sure what the best practices are.

For every single test case, do I need to open a new browser or do I set it up so that one test case can pick up where the previous test case left off, and use the browser state of the previous test case? Are there some general rules of thumb for this?

Initially I was thinking that opening a new browser for every test case would be too inefficient so I was trying to have the test cases run one after the other, but run order cannot be assigned in JUnit.😭 So now I am thinking that I need to make every test case completely independent and have some "set up" lines of code at the beginning of each test case and if applicable use @Before .

Is a good way to do it?

1. In setUpBeforeClass(){} create the browser
2. Use driver.get("specific url for test case"); at beginning of every test case. But this would be bad when changing between environments and changing urls.....

您可以使用以下方法删除测试之间的Cookie，从而节省时间：

driver.manage().deleteAllCookies();
