Agile Testing: Software Testing Practice

Introduction:

Agile testing is a software testing practice that follows the principles of the agile manifesto, emphasizing testing from the perspective of customers who will utilize the system. Agile testing does not emphasize rigidly defined testing procedures, but rather focuses on testing iteratively against newly developed code until quality is achieved from an end customer's perspective. In other words, the emphasis is shifted from "testers as quality police" to something more like "entire project team working toward demonstrable quality."

Agile development and testing is growing in popularity and smart QA/testing teams keep pace with current development trends. Agile testing tools vary from project management tools to automated testing

Agile Teams Automate Black Box and White Box Tests
For functional/acceptance tests, it’s most common for there to be a combination of white-box (under-the-covers) and UI automation (black-box) tests. The white-box tests tend to be less fragile, so are less costly to maintain, whereas the black-box UI-driven tests need to be leveraged judiciously due to the cost to develop and maintain the tests over time. Ideally, testers are involved in both, so that the black-box tests can supplement instead of duplicating white-box tests.
7. When Not to Use Automation in an Agile Environment
It's important to know when and when not to automate tests, this holds true no matter what methodology is used. If a test is only performed once then it shouldn't be automated. One-time tasks and exploratory testing/edge cases shouldn't be automated. Edge cases are, by definition, usually one-off test cases, and the effort to automate edge cases generally does not pay off. Exploratory tests are best used to gain knowledge of a new feature and then tweak or revise tests based on the new knowledge.
8. Switching from Waterfall to

More over, traditional test automation tools don’t work for an Agile context because they solve traditional problems, and those are different from the challenges facing Agile Automation teams. Automation in the early stages of an agile project is usually very tough, but as the system grows and evolves, some aspects settle and it becomes appropriate to deploy automation. So the choice of testing tools becomes critical for reaping the efficiency and quality benefits of agile.
Challenge 3: Script Development Phase
The Automation testers, developers, business analysts and project stakeholders all contribute to kick-off meetings where “user-stories” are selected to next sprint. Once the “user-stories” are selected for the sprint, they are used as the basis for a set of tests.
As functionality grows with each iteration, regression testing must be performed to ensure that existing functionality has not been impacted by the introduction of new functionality in each iteration cycle. The scale of the regression testing grows with each sprint and ensures that this remains a manageable task the test team use the test automation for the regression
