This commits reduces the execution time of the test WC_Tests_Paypal_Gateway_Request::test_request_url() from about 30s to about 6s (which is still super slow and even after this change this test is still the slowest in our test suite). This test creates several products that are needed to test different scenarios. To make it run faster, the code was changed to create the WC_Product objects without saving them to the database. Just interacting with the objects is enough to this test and skipping the database makes it run much faster. Other tests might benefit from the same technique.
This commit removes unnecessary clean up code form some unit tests. All database changes done during a test are automatically reverted after the test finishes, so it is not necessary to write code to manually remove them. This change simplifies the test code and make it run a bit faster.
This commit removes a bunch of unnecessary cleanup code from cart tests. All database changes are automatically reverted after each test, so it is not necessary to write code inside the test to manually revert the changes that were made. One test method was split into three different methods for clarity and to avoid having to revert database changes manually between each part of the test.
This change makes the tests easier to read but also reduced the execution time of the cart tests in about 15%.
This commit fixes a bug in WC_Customer_Download_Log_Data_Store::get_download_logs() that made impossible to change the order in which the query returned the results. This method accepts the arguments order_by and order, but it was ignoring them and always using the default values ('download_log_id' and 'ASC' respectively).
It also introduces a very basic unit test to cover the method main functionality and to make sure that the parameters order and orderby are not ignored anymore.
It seems that the modified method was inspired in WC_Customer_Download_Data_Store::get_downloads() before the same bug was fixed in #18620.
