Issue summary
The data needed for the automated test cases changes unpredictably
Category
Design
Examples
- Test data is obtained by anonymising customer data. This has some major disadvantages:
- The data must by anonymised (this can be tricky)
- You must be able to use different IDs or search criteria for every run
- you probably wont get just the data combination that you need for a special test case and if you add it, it will be overwritten next time you get a new batch of customer data
- different input data means different output data, so it will be more difficult to compare results - Test automation shares databases with testing or development
- After an update to the Software Under Test (SUT) the data is not compatible any longer
- Tests alter the data for following tests
Questions
How do you collect the necessary data?
Resolving Patterns
Most recommended:
- FRESH SETUP should help you in most cases
- DEDICATED RESOURCES: look up this pattern if you have to share resources
- WHOLE TEAM APPROACH: if your team follows an agile development process this is the pattern to use in order to avoid this kind of problems from the beginning
Other useful patterns:
- SHARE INFORMATION: use this pattern for better communication between development, testing and automation
- DESIGN FOR REUSE: this pattern should be used always
