There is a growing adoption within the IT industry with respect to the scrum and other agile methodologies. Each and every software development model, whether it’s Sequential or Spiral or Incremental or Agile, has a number of testing implications. Some of these implications challenge the fundamentals of testing.

We are trying to discuss those challenges to testing so that the client or the reader of this article can understand the issues faced with Scrum and Agile methodology in general. Also, suggesting some of the testing strategies which should be chosen to mitigate or reduce challenges and risks. As per our experience of testing different agile or scrum based projects, the following are the common challenges faced:

•    Dealing with volume and speed of change
•    Remaining effective during very short iterations
•    Receiving code after inconsistent and inadequate unit tested
•    Managing the increased regression risk
•    Managing Expectation
•    Holding to arbitrary sprint durations
•    Dealing with shifting Test Basis

We should carefully choose our testing strategies which can help dealing with mentioned challenges while working on such methodologies. 

•    Risk-based testing- It supports increased productivity since it reduces or eliminates testing where risk is low.

•    Automated Regression Testing- It helps to contain the regression risk associated allowing a higher rate of change.

•    Reactive Testing- It allows the testing team to explore various aspects of the system that risk-based or automated regression testing might miss.

•    Test driven development- This approach combines test-first development where you write a test before you just write enough code.

No doubt, Agile is a powerful tool for software and application development, not only providing benefits to the development team, but also providing a number of important business decisions which are beneficial to the clients. 

Agile helps project management deals with many of the most common project pitfalls (such as cost, schedule predictability and scope creep) in a more controlled and optimized manner. 

As discussed above, by reorganizing and re-envisioning the activities involved in custom software development, If one overcomes the testing challenges in Agile eco-system, one can achieve desired project objectives in a leaner and more business-focused way.
