- 3. 3Using Test Matrices for Routine IssuesAfter testing a simple numeric input field a few times, you’ve learned the drill. The boundary chart is reasonably easy to fill out for this.Use a test matrix to show/track a series of test cases that are essentially the same.For example, for most input fields, you’ll do a series of the same tests, checking how the field handles boundaries, unexpected characters, function keys, etc.
- 4. Creation of Test MatrixThe matrix is a concise way of showing the repeating tests. Put the objects that you’re testing on the rows. Show the tests on the columns. Check off the tests that you actually completed in the cells.
- 5. Typical Uses of Test MatricesYou can often re-use a matrix like this across the functionalities in products and projects.You can create matrices like this for a wide range of problems. Whenever you can specify multiple tests to be done on one function, and you expect to test several such functions, you can put the multiple tests on the matrix.
- 6. Typical Uses of Test MatricesMark a cell green if you ran the test and the functionality passed it. Mark the cell red if the functionality failed and write the bug number of the bug report for this bug.Write (in the cell) the automation number or identifier or file name if the test case has been automated.
- 7. MatricesProblems?What if your thinking gets out of date? (What if this program poses new issues, not covered by the standard tests?)Do you need to execute every test every time? (or ever?)What if the automation ID number changes?
- 9. I think you got it right ?This includes only the first few columns of a matrix that I’ve mentioned, but it gets across the idea.
