In the present era, the need of incorporating the frequent incoming changing requirements in the software product, in an efficient and effective manner, along with the delivery of a product, in a minimal possible time has made most of the organization, to adopt and implement the agile methodology of software development. Agile Development Methodology is an evolutionary approach, which provides the delivery of a software product in increments after each iterations (sprints) of short duration.
Agile Testing is one of the testing types, which follows the principles of agile methodology. Some of the features of agile testing are:
Although, the features and advantages associated with the agile testing, lures any of the testers, to be a part of the agile testing team, the professionals who are already engaged or had been the part of the agile testing team, are aware of the challenges and issues, common to this testing technique. Let's go through some of them:
Agile methodology or agile testing does not involve any sort of requirement gathering and its documentation. Thus, the non-availability of the documentation work, obstructs the agile testers, in verifying and validating the functionality or the features of a software, as they are unaware of the requirements, against which a software needs to be tested
The incoming requirements may bring small or large amount of changes in the already existing code after each iteration (sprint). Thus, the code are need to be verified and validated after each sprint, and thereby requires automation of regression test suites, an additional burden on the agile testing team.
Traditional automation tools are used to automate the testing of a fully developed software product, which may not required any further changes. When talking about the agile methodology, testing is to be carried out, from the beginning, along with the development, and it would not be feasible to automate testing at an early stage of the agile development. Further, automation may be introduced at a later stage, but still these traditional tools are not suitable for the agile environment. Selecting the right and suitable tools for automating the agile test environment, is the major challenge for the testing team.

The small quick sprints, and the need to deliver product after each sprint, forces the testing team to focus and emphasize only on the essential functionalities and the features, modified after each sprint. Therefore, majority of functionalities & features, could not be covered under the regression test suites.
Agile does not consists of any documentation work, still teams and stakeholders/client collaborates frequently after each sprint, to address various issues, relating to requirement gathering, analysis, changes, correction, etc. Still, agile needs good and proper communication between the teams, including clients, so as to easily understand and interpret the requirements. Further, a testing team need to have a proper communication with the development team, as they may aid the testing team, to understand the features and functionalities of a product, in carrying out the testing activities, in the absence of any documentation work, during each sprint.
