Domain Knowledge Empowers Testers to Perform Software Testing “Out of the Box”

Today, Software Testing is an industry which is growing exponentially and segmented into Services, Test Automation, Performance Testing, Security Testing Markets. It has grown from a mere phase in SDLC to what it is today over the years and it is still growing. So, software testers who are the core of the industry require more than basic Software Testing knowledge and skills to stay relevant in the industry.

If software testers equip themselves with domain knowledge, then they can think out of the box to step ahead of their peers. Yes! You read right, domain knowledge enables testers to think out of the box, let’s see how.

Domain Knowledge Enables Test Creation “Out of the Box”

To start testing an application, it is enough to know a few core concepts and a basic understanding of Software Testing. With this level, testers would be testing the application at a basic level which doesn’t uncover defects in complex scenarios. For example, testers with Banking domain knowledge understands the complex workflows of the Banking Software and with this understanding, testers can create test cases or test scenarios that uncovers complex defects. Banking Software Testing performed by testers without domain knowledge results in defect leakage into the production. Defect leakage impacts the core functionality of Banking Software and makes customer experience and business to suffer.

Defect leakage is directly proportional to how effective test cases were created. Let’s understand test case or scenario creation outcome with domain knowledge. Functional Requirement serves as the base document for test case creation, accompanied by UML diagram inputs and application KT or training. By accessing the application and understanding the end-to-end workflows, testers with domain knowledge can put all their thoughts around test scenarios on the paper first. They can create as many as scenarios that result in maximum functional coverage. Later, a functional requirement document, UML diagrams, and application KT or training will refine the test scenarios created. Not just positive scenarios, Domain Knowledge enables creating negative scenarios out of the box.

Domain Knowledge can be helpful in Test Creation “Out of the Box”, which enables maximum functional coverage and minimized defect leakage.

Domain Knowledge Enables Defect Detection “Out of the Box”

Providing insights on the impact of a defect on the functionality is another important aspect that testers with domain knowledge can do. They understand the data flow of the end-to-end workflows and analyze the impact of a defect in a module on the specific functionality. This kind of analysis would help in understanding the defect leakage impact before a release and taking precautionary measures.

Exploratory Testing is a rigorous testing activity, performed to explore the defects in an application without leveraging any test cases. Exploratory Testing is completely dependent on tester out of the box thinking ability. Testers with domain knowledge can replicate different users’ behavior to identify defects while performing exploratory testing. Several years of experience in testing similar kind of applications empower testers to predict the areas of an application which are prone to more defects. Hence, more exploratory testing time will be spent on those areas to find more complex defects.

Domain Knowledge Improves Application Quality “Out of the Box”

Testers with domain knowledge contribute more than test creation and defect detection, they can be helpful in defect fixing. This saves a lot of time and enables faster time-to-market with improved productivity and overall application quality.

A strong defect fixing plan is the core of application quality. Testers with domain knowledge can prioritize defects to be fixed by analyzing the impact. They will also analyze the severity of the defect by understanding the expected output.

Overall application’s usability and functionality will be significantly improved when enhancements suggested by testers are incorporated as they replicate user behavior. Testers require domain knowledge to think of enhancements that can bring improvement.

Domain Knowledge combined with Testing skill explores the possibilities to improve user experience and application quality.
