When a software development team switches its approach to an Agile framework like Scrum, the place of software testing changes. In his book Scrum Product Ownership, Robert Galen describes the new role of software testers in Agile teams and their relationships with the product owners.
There is a value in writing tests and there is also a cost. The currency is time. The trade-offs are difficult to evaluate in software testing because cost and value are often seen by different people. The writer of the test bears much of the short term cost while long term benefits and cost are borne by the rest of the team.
DevOps is based on continuous delivery and anything that breaks the continuity is a bottleneck. While Agile and DevOps have become common terms in Development and Testing organizations, manual build and deployment processes are still causing problems along with integration and testing.
The management of test environments is an area mostly neglected in software development projects. In this article, Niall Crawford discusses the basic requirements of test environment management and explains the benefits this activity provides.
The evolution of software from a simple application running in an isolated system to a multi-node solution in a network and now to geographically distributed cloud solution with hundreds or thousands of nodes, has brought about its own challenges in terms of testing. Testing strategies which works well in one model is not really applicable to others. While many of the tests for a cloud hosted solution can be done by replicating a subset of the actual production environment, some test to be effective need a production like environment.
Learn about the effectiveness of coverage as a technique for evaluating quality of test suite. This presentation shows the utility of coverage by considering its correlation with mutation score, and also shows that coverage is a significant defense against bugs. It also critiques the effectiveness of mutation score as a criteria for test suite quality.
The possibilities to write parametrized tests have changed and improved a lot with the release of JUnit 5, the open source unit testing tool for Java. In his blog post “Using JUnit 5 Parameterized Tests, Argument Sources and Converters”, Micha Kops provides an overview covers all new types of parameter sources for JUnit 5 tests as well as the new conversion API for test arguments.
