What is Test Strategy? Types of strategies with examples

There is no way to run thousands of tests quickly, and testers must prioritize what they need to test. This is where a risk-based analytical test strategy can help you decide how to allocate time and effort in each sprint. A new class of tools called Quality Intelligence Platforms are providing a more scientific approach to test prioritization. Smoke and sanity testing come before regression tests and can save time for testing teams. Sanity testing is a run-through of the basic functionality of an application, prior to the additional testing of a new release, which informally confirms that functionality works as planned.

Depending on product and organization’s requirements, two or more techniques may be combined. Let us consider a situation where the compatibility of any web based application with possible browsers is to be tested. Here the application owner would provide a list of browsers and their versions in order of priority.

What is regression testing, and why do we need it?

Instead of blindly following the templates, consider what will work best for your product. Every product has different specification, so you need to stick to what you know works best for you. Here are a few tips you might find helpful when preparing a test strategy document. In this informal method, the inputs from cross-functional stakeholders are not given due consideration.

Modifications that have an impact on core features, or those that significantly alter how the application works, should always be the top priority. Identifying the impact and risk of the latest code change is key to building a solid regression test. Conduct code review sessions to identify the components or modules that were changed, as well as their impacts on the existing features.

Proactive Test Approach

Depending on the type of project and related requirements, the risk can be higher or lower. For instance, financial and medical sectors tend to lie on the high-risk spectrum since they need the most precision. Therefore, any product meant for these industries must undergo stringent testing. A process or standard-compliant testing approach adheres to pre-defined frameworks, standards, and processes to facilitate compliant and consistent testing practices.

  • Cap off these test approach best practices with impeccable imitation between the developer environment and the end-user environment.
  • This is a proper solution for large-scale quality assurance teams with advanced testers having expertise and experience.
  • Therefore, any product meant for these industries must undergo stringent testing.
  • A good strategy for regression testing reduces testing time and effort and enhances the product quality, making it fully correspond to the customer’s needs.
  • The choice of an approach depends on the scope of changes, the methodology and the stage of product delivery process.

By picking out the related areas, you can apply limited and relevant test cases to reduce both the time and effort invested in regression testing. When a team plans software testing, including the potential risks within the software project is essential. The procedure to detect such risks is explained earlier in ‘The Identification Phase’ section of this analytical test strategy tutorial. While testing is in progress, the Senior Manager, Product Manager, Project Manager, and other stakeholders can monitor and deal with the Software Development Life Cycle due to the risk-based testing.

Regression testing and other types of testing

Agile teams move fast, and regression test suites can become a major burden. Here the testing team defines the testing conditions to be covered after analyzing the test basis, be it risks or requirements, etc. A test strategy refers to an organization-level document describing the testing approach, also known as what the testing team needs to achieve and how they can achieve it. Instead of outlining project-specific testing needs, this document presents some common testing principles for all projects. Regression testing and retesting are both important activities in software testing, but they serve different purposes.

In the agile context, testing is required to develop with every sprint, and testers need to ensure that the new changes don’t impact the existing functionality of the application. There are numerous and frequent build cycles in agile contexts, along with continuous changes being added to the app, which makes regression testing more critical in the agile landscape. To achieve success in an agile landscape, the testing team must build the regression suite from the onset of the product development and continue developing these alongside development sprints. Testers can practice effective resource allocation by adopting risk-based testing approaches that emphasize areas with a high likelihood of impacting the quality of a system. Testers can easily achieve a broad test coverage and reduce repetitive regression testing by leveraging the power of sophisticated automation frameworks. This regression testing approach comprises of all regression test cases covering the product in full.

Questions to ask before every Software Release

Testers must be clear on how frequently a bug occurs and how it affects the software. Make sure that reports from your regression testing tools are transparent, and that you can see the real results of test executions over time. There are various tools out there to help you organize and scale your regression testing processes, such as CI/CD tools.

You can’t run automation tests without knowing how to organize and execute them for quick, accurate,… Front-end refers to the user-facing part of an app, which is the primary interface for content consumption and business transactions. Front End Testing is a key part of any SDLC as it validates GUI elements are functioning as expected. Compare and track what the differences are when processes and tests are run on different platforms.

Depending on how much a tester knows about a particular system and current testing techniques, they can make an informed decision regarding testing techniques and approaches. Some of the processes in this approach include ensuring alignment between https://www.globalcloudteam.com/ industry standards and testing activities and meeting set quality criteria. Testers usually conduct testing in a controlled and structured manner which ensures the auditability, reproducibility, and traceability of various activities.

This is conducted to check how the code reacts when a fresh code is added to the program. In order to conduct this test, the sub-set from existing cases is used to make it efficient and cost-effective. Then tests the impact regions in A and C as well to identify how they have been affected. This is a very focused approach regression averse where only the modified section goes under the regression test instead of the impact region. Testers should communicate with product owners to monitor changes in requirements and asses them. They should communicate with developers to understand which so they know what changes were made during an iteration.

Automated Regression Testing: Important Considerations

Strategy and investment must be considered two significant factors when venturing into a software testing project. Determining the overall project investment is impossible without knowing what techniques and tools are required to test a website or app. For example, suppose you have a checklist of the input and output for the testing; then, you can methodically design and implement the model based on your checklist and execute the test.
