To benefit most from agile, you need efficient test automation to quickly validate incremental changes and make sure you aren’t building on top of broken functionality.
The testing pyramid, shown to the right, provides a blueprint for how to build a scalable agile testing strategy. The first step is establishing a solid practice of static code analysis that is effective in preventing reliability and security defects from entering the code base. Next is the creation of a comprehensive foundation of unit tests to ensure good code design and identify regressions at the earliest stage. Moving up the pyramid, API/service-level tests enable fully automated testing of your business logic, and at the top, a minimal number of brittle and expensive end-to-end UI-centric or manual tests.
Many organizations start by focusing on end-to-end UI testing and while UI testing is intuitive to perform, it fails to provide the rapid feedback or granular data required for agile teams to quickly identify, diagnose, and remediate identified regressions. Parasoft provides tools to help organizations modernize their approach to testing, making the pyramid a reality, for a scalable testing practice that can be efficiently executed to accelerate delivery of Agile projects.
So, what does the ideal testing strategy for agile software projects look like? Read more in the sections below.
