When development leaves ample room for testing, it improves software reliability and high-quality applications are delivered with few errors. The sooner development teams receive test feedback, the sooner they can address issues such as: Early software testing uncovers problems before a product goes to market. Though testing itself costs money, companies can save millions per year in development and support if they have a good testing technique and QA processes in place. What’s more, they impacted 4.4 billion customers. Software failures in the US cost the economy USD 1.1 trillion in assets in 2016. In extreme cases, a bug or defect can degrade interconnected systems or cause serious malfunctions.Ĭonsider Nissan having to recall over 1 million cars due to a software defect in the airbag sensor detectors, or a software bug that caused the failure of a USD 1.2 billion military satellite launch. Late delivery or software defects can damage a brand’s reputation, which leads to frustrated and lost customers. Testing effectiveness is optimized by running the fewest number of tests to find the largest number of defects.įew can argue against the need for quality control when developing software. A test management plan helps to prioritize which types of testing provide the most value-given available time and resources. Just as important, exploratory testing helps a tester or testing team uncover hard-to-predict scenarios and situations that can lead to software errors.Įven a simple application can be subject to a large number and variety of tests. In each case, validating base requirements is a critical assessment. Usability testing: Validating how well a customer can use a system or web application to complete a task.Stress testing is considered to be a type of non-functional testing. Stress testing: Testing how much strain the system can take before it fails.
Sanity testing can be used to verify menus, functions and commands at the surface level, when there is no time for a full regression test. Regression testing: Checking whether new features break or degrade functionality.Load testing, for example, is used to evaluate performance under real-life load conditions. Performance testing: Testing how the software runs under different workloads.Black-box testing is a common way to verify functions. Functional testing: Checking functions by emulating business scenarios, based on functional requirements.A unit is the smallest testable component of an application. Unit testing: Validating that each software unit runs as expected.Integration testing: Ensuring that software components or functions operate together.Code review: Confirming that new and modified software is following an organization’s coding standards and adheres to its best practices.Acceptance testing: Verifying whether the whole system works as intended.There are many different types of software tests, each with specific objectives and strategies:
