Test Data Preparation: Tips and Tricks - SQA Days 22 - Saint Petersburg

Performance is one of the main painful areas of Selenium test. One of the most important points of improvements is Test Data creation and clean up. In this talk, we will discuss how to create test data via HTTP requests and clean it after the test run.

Optimization of the Selenium suite is important for us. In this talk, I will present how to create HTTP requests builder to create and clean up test data after the Selenium test run. This will help you to prepare particular situation before logging into web application via Selenium and test the exact functionality you need. After the test run the cleanup should be done again with HTTP request to avoid performance issues and minimize flakiness for other tests in the suite.

In addition, I will also present how to use HTTP code to set up session cookie and make configurations then extract cookie and pass to Selenium, which will help to skip logging in from UI for every test.

    What is Test Data? Why is it Important? 1 What is Test Data Generation? 2 Why should test data be created before test execution? 3 Object class generation based on JSON 4 Maintaining responses of HTTP requests using Jackson library 5 How to store login info in browser to avoid logging in from UI 6 Q&A 7 Test Data Preparation via HTTP requests 4
  2. SQA Days 2017 3 WHAT IS TEST DATA? WHY IS

    IT IMPORTANT? 1. A single Selenium test should test one and only thing. A bug in another part of the application that is not exactly related to the test should not cause the test to fail. 2. Every test should be independent. The test outcome should not affected by another test in the suite. 3. Make a faster tests. As quicker test suite as much useful it is. 4. Every test should create and clean the data before and the after the test run. 5. We should not do the same action from the UI for every test case (e.g. login action) When we are talking about best practice in Selenium test, some of things often come up are:
  3. SQA Days 2017 4 WHAT IS TEST DATA? WHY IS

    IT IMPORTANT? Each test run does the following Run the test Test initialize Test clean up
  4. SQA Days 2017 5 WHAT IS TEST DATA GENERATION? Test

    Data Generators based on their approaches are typically classified into Random Test Data Generators Goal Oriented Generators Intelligent Test Data Generators Pathwise Data Generators TD
  5. SQA Days 2017 6 WHY SHOULD TEST DATA BE CREATED

    BEFORE TEST EXECUTION? ! ! Login  Submissions   Pages Navigation  TD The reason for this is that Selenium tests often involve setups that may include Only after doing those things you are ready to assert on some aspect of the website  Actions Sign up   Interactions
  6. SQA Days 2017 8 BASIC IDEA BEHIND COMBINING THESE TOOLS

    These are the steps how to get started with OKHttp and Test Data Preparation FIRST STEP We will be creating instances of HTTP for various methods like GET,PUT,POST etc. by mentioning the request URL SECOND STEP We will be composing the request body as JSON THIRD STEP Execute the desired HTTP method when headers etc are all set FOURTH STEP Capture the response and convert it to a JSON object. FIFTH STEP Desterialize JSON to any Java Object
  7. SQA Days 2017 15 JACKSON- CONVERT JAVA OBJECT TO /

    FROM JSON 15 Let’s see how to use Jackson 2.x to convert Java object to / from JSON. Convert Java object to JSON  Convert JSON to Java object 

    is the best selector to use # Preferred selector order : id > name > css > xpath
  10. SQA Days 2017 28 BEST PRACTICE VS. BAD PRACTICE Automate

    CAPTCHAS # CAPTCHAs can be bypassed using two strategies: • The first idea is to disable CAPTCHAs in your test environment. • The second idea is to add a hook to allow tests to bypass the CAPTCHA.

    Specific Application User per Test "
  12. SQA Days 2017 31 BEST PRACTICE VS. BAD PRACTICE Gmail

    and Facbook Logins # WebDriver is not the ideal choice to automate login into websites like Gmail and Facebook, firstly because it is against their policy and secondly because it is slow and unreliable. The most appropriate choice would be to use the API that these websites provide.
  13. SQA Days 2017 32 BEST PRACTICE VS. BAD PRACTICE Performance

    Testing Using WebDriver # Using selenium WebDriver is not an ideal choice for performance testing, not because it can’t do it but because it is not meant for this job ultimately tester might not get good results.
