Agile software development is quickly becoming the preferred way to build mission-critical software systems. However, if it is not implemented properly customers can run the risk of increasing costs and loss of quality instead of making teams more effective. There are frequently challenges among stakeholders, problems with communication, compressed schedules, and various types of testing each with its own set of requirements, schedules, and procedures. The complexity of testing is increasing as applications themselves become more complex and initial testing is increasingly difficult—trying to run all these tests in an agile environment compounds the problem even further. By defining dependencies among tests you can realistically emulate real-life business processes and make it easier to maintain and reuse the tests.
