By Software testing solutions is an essential part of any product development process. It can help prevent the release of poor quality products, which can have devastating consequences. However, just because a piece of software passes all the tests doesn’t mean that it is free from bugs. To achieve a truly bug-free product, it must be tested thoroughly.
Principles Of QA
Testing software is a complex and resource-intensive process. Applying these thoughtful principles to your tests can help you become more efficient and focused, and improve the quality of your overall testing strategy.
Trying to test every possible combination of inputs and pre-conditions and phase of QA ensures is known as exhaustive testing, and it’s nearly impossible for any team to achieve. For example, if you’re testing a simple screen that takes two numbers and prints their sum, it would take infinite time to write test cases for all combinations of valid and invalid inputs.
This principle helps set stakeholder expectations – it’s easier to find defects in untested functionality than fully developed functionality that appears bug-free on the surface. In addition, finding an error in untested functionality is usually cheaper than fixing errors found after deploying the software to production environments.
Requirements Analysis
The requirements analysis phase of QA ensures that the product will meet its intended purpose. This is achieved by gathering and analyzing requirements from the stakeholders and end-users of the software system. Using techniques such as interviewing, brainstorming and workshops can help to identify and gather these requirements.
Another technique that can be useful in this phase is the failure test, which involves exposing products to various stresses and examining how they perform under those conditions. This can help to identify many issues that may not have been evident during the requirements analysis stage.
Once the requirements are gathered and documented, they must be reviewed and prioritized to determine which are most critical. This can also be a good opportunity to resolve any conflicting requirements.
Test Planning
A test plan is the backbone of a testing project. It defines which modules will be tested, how and when, and provides clarity for QAs. Without a well-crafted plan, it is easy for QAs to get lost with undefined goals and vague deadlines, which hamper accurate and fast app testing solutions.
A good test plan with QAs will contain an in-scope and out-of-scope list, methods of testing, the equipment required for the tests, and a pass/fail criteria. The plan should also provide an estimated time to complete the tests and include any risks associated with them.
It should be easily readable and avoid heavy technical jargon, as most readers will be business-oriented. It should also be flexible enough to adapt to changes in a project without having to create new documentation.
Test Design
The test phase of QA ensures design phase involves identifying the number of tests needed and ways they will be approached. It also includes determining what test data will be used. QA specialists who are familiar with test design techniques find it much easier to create efficient test suites.
Testing for invalid input values is important because a small number of incorrect inputs can lead to catastrophic errors such as system crashes and data loss. It is also crucial to test for a variety of conditions such as temperature, humidity and vibration.
STD (state, transition and event) testing is a process for analyzing the behavior of a software program using a state graph. It shows all possible states, events that can trigger a state, and the transitions between them. It also helps in identifying test cases that can cover all possible combinations of input values.
Test Execution
Test execution is the actual validation of the AUT based on prepared test cases and comparing the expected results with those obtained. This is a key testing phase, and the testers must be hypercritical, relentless and creative to detect bugs.
This phase involves manually executing the tests and automating them as well using scripts. All steps and activities should be documented in a tracker system like JIRA or Excel sheet. Each bug that is found goes through a defect cycle that includes states like new, assigned, verified, retest and closed.
Once all of these criteria are met, the testing process is considered to be over. However, this doesn’t necessarily mean that the product is production ready. There might still be some low priority defects that need to be fixed before the product can be rolled out.
