Website Testing
Web testing is the name given to software testing that focuses on web applications. Complete testing of a web-based system before going live can help address issues before the system is revealed to the public. Issues may include the security of the web application, the basic functionality of the site, its accessibility to handicapped users and fully able users, its ability to adapt to the multitude of desktops, devices, and operating systems, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing.
A WAPT faces various challenges during testing and should be able to conduct tests for:
- Browser compatibility
- Operating System compatibility
- Windows application compatibility where required
Database Testing is a type of software testing that checks the schema, tables, triggers, etc. of the Database under test. It also checks data integrity and consistency. It may involve creating complex queries to load/stress test the Database and check its responsiveness.
Database Testing is Important in software testing because it ensures data values and information received and stored into database are valid or not. Database testing helps to save data loss, saves aborted transaction data and no unauthorized access to the information. Database is important for any software application hence testers must have good knowledge of SQL for database testing.
The 3 types of Database Testing are:
- Structural Testing
- Functional Testing
- Non-functional Testing
Functional testing is meant to ensure that software behaves as it should. Therefore, it is largely based on software requirements. For example, if security requirements state that the length of any user input must be checked, then functional testing is part of the process of determining whether this requirement was implemented and whether it works correctly.
Analogously, risk-based testing is based on software risks, and each test is intended to probe a specific risk that was previously identified through risk analysis. A simple example is that in many web-based applications, there is a risk of injection attacks, where an attacker fools the server into displaying results of arbitrary SQL queries. A risk-based test might actually try to carry out an injection attack, or at least provide evidence that such an attack is possible. For a more complex example, consider the case where risk analysis determines that there are ambiguous requirements. In this case, testers must determine how the ambiguous requirements might manifest themselves as vulnerabilities. The actual tests are then aimed at probing those vulnerabilities.
Usability testing is the practice of testing how easy a design is to use with a group of representative users. It usually involves observing users as they attempt to complete tasks and can be done for different types of designs. It is often conducted repeatedly, from early development until a product’s release.
Through usability testing, you can find design flaws you might otherwise overlook. When you watch how test users behave while they try to execute tasks, you’ll get vital insights into how well your design/product works. Then, you can leverage these insights to make improvements. Whenever you run a usability test, your chief objectives are to:
1) Determine whether testers can complete tasks successfully and independently.
2) Assess their performance and mental state as they try to complete tasks, to see how well your design works.
3) See how much users enjoy using it.
4) Identify problems and their severity.
5) Find solutions.
