puzzle Writing Tests: Action Abstraction

Keywords have become a popular way of writing tests. Hans Buwalda used keywords to devise the Action Based Testing method in which tests are written as sequences of “actions” represented with keywords. However, keywords are just a physical representation of actions, and there are other ways to do this.

How do you test a tool to be used for automated testing? If a tool executes an automated test that generates keyboard and mouse events to replay user actions, can the test emulate user input and control another instance of the tool to automatically record and play another test? Here's how you test the test tool.

There are many new trends in online payment technology, so the amount of data passing through and stored across varying systems is growing, requiring new standards for how data is captured, stored, used, and destroyed. Testers especially need to consider vulnerabilities related to data privacy and cyber security.

AI traffic light Testing Artificial Intelligence: How Low Can You Go?

Artificial intelligence (AI) is propelling to the forefront once more. With the growing importance of AI comes the question: How do I test it? AI systems do not necessarily behave predictably. This means that traditional test cases of the form "do this, expect that" are not always sufficient.

We tend to contrast automated and manual testing, but really, they should support each other. The key is to define what our testing objectives are, then build the solution needed to achieve them—probably a combination of manual and automated testing. We should not let the method become more important than the results.

Four checkboxes with two of them checked Questions to Ask during Test Selection for Automated Tests

We use test design techniques to answer the questions “What do I need to test?” and “What tests should I perform?” We try to ensure test coverage during test automation too, except that choosing poorly creates slower builds and unreliable information about product quality. Here are some guidelines for test selection.
