Welcome everyone to Exchange study

"""A new test client is created in the SetUp () method and a new database is initialized. This method is called before each independent test function is run. The function of the TearDown () method is to close the file at the end of the test and delete the database file from the file system. In addition, the testing flag is turned on in the settings, which means that error snapping is turned off on request, so that better error reporting can be obtained when the test request is executed. The test client will provide us with a simple application interface. We can send a test request to the app through this interface. The client can also track cookies. Because SQLite3 is file system-based, we can easily use the temporary file module to create a temporary database and initialize it. The Mkstemp () function returns two things: a low-level file handle and a random filename. This file name will be followed by our database name. We must save the handle to DB_FD so that we can use the Os.close () function to close the file later. """    classflaskrtestcase (unittest.
