copied!<p>I've encountered several situations where TDD makes me crazy. To name some:</p> <ul> <li><p>Test case maintainability: </p> <p>If you're in a big enterprise, many chances are that you don't have to write the test cases yourself or at least most of them are written by someone else when you enter the company. An application's features changes from time to time and if you don't have a system in place, such as HP Quality Center, to track them, you'll turn crazy in no time.</p> <p>This also means that it'll take new team members a fair amount of time to grab what's going on with the test cases. In turn, this can be translated into more money needed.</p></li> <li><p>Test automation complexity: </p> <p>If you automate some or all of the test cases into machine-runnable test scripts, you will have to make sure these test scripts are in sync with their corresponding manual test cases and in line with the application changes.</p> <p>Also, you'll spend time to debug the codes that help you catch bugs. In my opinion, most of these bugs come from the testing team's failure to reflect the application changes in the automation test script. Changes in business logic, GUI and other internal stuff can make your scripts stop running or running unreliably. Sometimes the changes are very subtle and difficult to detect. Once all of my scripts report failure because they based their calculation on information from table 1 while table 1 was now table 2 (because someone swapped the name of the table objects in the application code). </p></li> </ul>
