    I hope the difference is clear between the two developers in the previous section. Eleanor used automated tests and systematically and effectively engineered test cases. She broke down the requirements into small parts and used them to derive test cases, applying a technique called domain testing. When she was done with the specification, she focused on the…

    The developer community no longer needs to argue about the importance of software testing. Every software developer understands that software failures may cause severe damage to businesses, people, or even society as a whole. And although software developers once were primarily responsible for building software systems, today they are also responsible for the quality of…

    Once you have made a selection, you have to roll out your new tool. This is usually done within the context of a pilot project in order to verify the tool’s usefulness in a real-world, project-based situation. A pilot project should be led and implemented by persons who were not involved in the tool selection…

    Once you have decided which test tasks you want to automate, you can begin the tool selection process. Because the cost of investing in a new tool can be very high (see above), you need to plan the process carefully. The tool selection process comprise five steps: Selection criteria In Step 1, the following criteria influence…

    Basic Considerations and Principles Some of the tools listed above (such as comparators or coverage analyzers) are already built into several operating systems (Linux, for example), enabling testers to perform basic testing using “onboard” tools. However, built-in tools often have fairly limited functionality, so you will usually need additional, specialized tools to test effectively. As…

    Software automation tool selection, purchase, and maintenance costs money, while acquiring appropriate hardware and training staff to use them uses further resources. The cost of rolling out a complex tool to a large number of workstations can quickly run into six figures. As with any other investment, the planned amortization period of a new testing…

    System access and data security Tools are also available to check for security vulnerabilities6 that could be used to gain unauthorized access to a system. Anti-virus apps and firewalls belong to this category of tool, as they produce logs that can be used to identify security flaws. Tests that reveal such flaws or check whether they…

    Load and performance tests are necessary when a system has to execute large numbers of parallel requests or transactions (load), whereby predefined maximum response times (performance) are not to be exceeded. Real-time systems, most client/server systems, and web-based or cloud-based systems have to fulfill these kinds of requirements. Measuring response times Performance tests verify how…

    Tools take over repetitious testing tasks People who refer to “test tools” are often actually referring to the tools used to automate dynamic testing. These are tools that relieve testers of repetitious “mechanical” testing tasks such as providing a test object with test data, recording the test object’s reactions, and logging the test process. Probe…
