The pytest framework makes it easy to write small tests, yet scales to support complex functional testing For that reason, with Pytest you can create conftest.py that launches a single Spark session for all of your tests and when all of them were run, the session is closed. A test case may also include Post - Conditions which specifies anything that applies after the test case completes. Sometimes a test session might get stuck and there might be no easy way to figure out which test got stuck, for example if pytest was run in quiet mode (-q) or you don’t have access to the console output.This is particularly a problem if the problem happens only sporadically, the famous “flaky” kind of tests.

For our test case, a pre-condition would be to have a browser installed to have access to the site under test. A framework makes it easy to write small tests, yet scales to support complex functional testing for applications and libraries. It is popular than the other available frameworks because of its attractive features. Level 2: This is the practical stage in which writing cases depend on the actual functional and system flow of the application. In the larger Python ecosystem, there are a lot of testing tools.

As Pytest is a command-line tool it detects the tests written automatically, just we have to name the test cases with a prefix test and it will execute the test cases and will get the results. a < 10 In order to make the session visible for tests, you should decorate the functions with Pytest fixtures. API is the acronym for Application Programming Interface.It is a set of rules that allow programs to talk to each other. In this post I will explain and go over how I personally write functional tests for my AWS Lambda functions.
