Installability testing is a type of non-functional testing that focuses on verifying that the software can be installed, upgraded, and uninstalled without errors or interruptions1. It is usually performed by a technical test analyst who has knowledge of the installation requirements, dependencies, and configurations2. The main objectives of installability testing are to ensure that the software is compatible with different platforms, environments, and hardware specifications, and that the installation and de-installation processes are functional, reliable, and secure3. Usability issues, such as the clarity, simplicity, and efficiency of the installation and de-installation user interfaces, are not the primary concern of installability testing, and may be better addressed by other types of testing, such as usability testing or user acceptance testing4. References = Installation testing - Wikipedia; ISTQB Advanced Level Technical Test Analyst Syllabus 2019, section 4.3.2; Mastering Installability Testing: A Key Software Quality Assurance Process; Installation Testing | Complete Overview Of Installation Testing

Classification trees are a visual way of identifying test objects and data, and pairwise testing is a technique of generating test cases that cover all possible pairs of values from different classifications. Classification trees support pairwise testing by:

• Helping to identify inputs to be used by the pairwise test technique, as each class represents a possible value for a test parameter.
• Showing the combinations needed to cover all-pairs, as each test case is a selection of one class from each classification.
• Helping to identify particular combinations of interest, as the test engineer can use the tree structure to group or prioritize classes based on their relevance or risk. References = ISTQB Advanced Level Test Analyst Syllabus 2019, section 3.2.3; Smarter Test Design with Classification Trees and Pairwise Techniques, slides 6-12.

A usability review is a technique that evaluates the usability of a system or product based on a set of criteria or heuristics, without involving the actual users. It can be performed by experts or peers, and it can identify potential usability problems and suggest improvements. A usability review is suitable for situations where the availability of users is limited or impractical, and it can provide quick and low-costfeedback. References = ISTQB Certified Tester Advanced Level Syllabus Technical Test Analyst, page 81, section 5.3.2.2.
