Five Common Problems With your Regression Testing Strategy

Value Transformation consults on the topics that we provide training and much more. Consultations can be direct or on your site, or remotely via telephone, Skype or other media. In either approach, our staff will work as a team member providing years of hard acquired experience into your team building capability along the way. In some cases, the test policy will be complementary to or a component of a broader quality policy. This quality policy describes management’s overall values and goals related to quality.

Ask the development team what they worked on or changed in the last release, or use quality intelligence platforms. They can help you on areas of the code which are really likely to have experienced regressions. The software needs to be operated on real devices, and the system has to be run in its entirety to find all bugs. Additionally, static tests must be run not just by technical personnel but other stakeholders. Business domain experts must review requirements, system architects must review design, and so on.

Process-compliant Test Strategy:

For example, the statistics below from an Ixia slide deck show that the cost of fixing a bug in production is 31X higher than fixing it at the build stage. Cut Failed Tests Troubleshooting Time Only troubleshoot code changes-related failed tests. 10 Test Automation Best Practices to follow You can’t run automation tests without knowing how to organize and execute them for quick, accurate,… Most teams do not have access to an in-house lab with the requisite number and variety of device-OS combinations for real-world testing. Focus on fully integrated systems rather than individual components. This is because it is possible to gauge system behavior from a user’s eyes only after it has been assembled and integrated to a significant extent.

Risk analysis can be used to determine test techniques used, the extent of testing carried out, prioritize testing in attempt to find critical defects. Risk Management can be used to provide a disciplined approach to assess risks, determine which are important to address, and implement actions to deal with risks. Testing does not exist in isolation; test activities are related to software development activities.

Risk Analysis (Includes Quantitative and Qualitative Analysis)

Different development life cycle models need different approaches to testing. One can’t change the test strategy once it’s been written, and it’s been accepted by the Project Manager and development team. The beginning of the test strategy document presents a concise overview of testing activities and phases as well as projects. Include information about the timelines, various testing stages, and procedures to offer the summary and structure of the entire document. This section should also explain how to use the document and who is responsible for its review and approval. This type of strategy employs models to design and execute tests and compare the results to the sample.

Examples of non-functional requirements can be performance, volume and security requirements. Exploratory testing has become an indispensable part of the modern Agile methodology to get quick feedback and result. It can be a significant change for testers familiar with or prefer the old school method of relying on well-documented requirements upfront. Exploratory testing in agile is quick to implement and fluid in its approach.

In the worst case scenario, a product may be so defective that it cannot be reworked and must be completely scrapped this would cause serious harm to the company’s reputation. Identify what kind of problems are crucial to the product objectives. Critical factors of similar/related previous projects that caused problems/issues. Features or functionalities were added to the product design in the last minute. Institutionalization and the achievement of other specific objectives established such as cost, schedule, and quality objectives.

The repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes. If the same tests are repeated over and over again, eventually the same set of test cases will no longer find any new defects. To find defects early, testing activities shall be started as early as possible in the SDLC, and shall be focused on defined objectives. Describe the test approach and tools needed for performance, load, and security testing.


And examples covering all non-functional attributes (volume, performance, stress, security…). On Agile projects, we also need different Test Levels and Definition of Done for each of them. Often we only think about DoD when we talk about User Stories, but we have to think about it for Test Levels, User Stories, Features, Iterations and Release. Interfaces between system and users, other systems, external data repositories, etc.

Test analysis and design is the activity during which general testing objectives are transformed into tangible test conditions and test cases. The activity of defining the objectives of testing and the specification of test activities in order to meet the objectives and mission. Project risks are risks surrounding the project’s capability to deliver its objectives. The person responsible for project management of testing activities and resources, and evaluation of a test object. The individual who directs, controls, administers, plans and regulates the evaluation of a test object.

Test design can use all dynamic test techniques discussed in Foundation, Advanced Test Analyst, and Advanced Technical Test Analyst, influenced by the results of the previous tests. Risk monitoring process helps in keeping track of the identified risks, and reducing the impacts of residual risks. Risk profiling is a process for finding the optimal level of investment risk for the client considering the risk required, risk capacity and risk tolerance. Prime factors or issues of Similar/related projects that that had a huge impact on the operation and maintenance expenses. G4 & G5 demonstrates’s the system meets the functional and non-functional requirements . Risk management strategy is used to identifying, analyzing, and mitigating risks.

White Box Techniques

Due to unhandled circumstances in the code, the test environment database may encounter issues. The tester also needs to have good knowledge and understanding of the software under test, the business domain, how the software is used, and how to determine when the system fails. During test execution, the tester uses creativity, intuition, cognition, and skill to find potential issues with the product. The quality of the tests depends on the testers’ ability to ask relevant questions about what to test.

Whether you want to be a better test manager, or gain useful knowledge of the software testing as a whole, A Test Manager’s Guide is the software testing book for you. The software Test Strategy is a high-level description of the test levels to be performed and the testing within those levels for an organization or Program. For example, by designing re-usable testware and by extensive automation of testing at one or more test levels.

Definitely the talk will bring good value to software testing audiences especially test managers. Testers, developers, project managers and higher management can benefit from the talk in the way that they understand and facilitate software testing methodologies in software development life cycle. A Test Strategy is a set of instructions, guidelines or principles that determine the test design and how the testing process will be carried out. Documents like test plans derive their content from the test strategy document. Deciding on the right test approach involves the careful consideration of the objectives of testing, goals of the project, and overall risk assessment. It provides a starting point to plan the test process and to select the test design techniques and testing types to be applied for the project.

During exploratory testing, the results of the most recent tests guide the next test. For example, You might use the IEEE 829 standard for testing using books or fill in the methodological gaps. This section describes the software and hardware that will be employed to run various tests. To achieve the best results and create a realistic environment, companies use actual devices, browsers, and operating systems. Testing using simulators can be a cost-effective alternative but will never fully emulate real-life conditions. This paragraph describes which risks are likely to occur during the testing procedures, their probabilities and outcomes, as well as mitigation strategies.

  • To perform exploratory testing, we need tools to create the test plans, store the test results and record the sessions and issues.
  • Based on the analysis, we can decide if the risks require a response.
  • The topic areas upon which we mentor range from project management to product management and line management.
  • Thomson Reuters Platform Thomson Reuters product, Cortellis, is an enterprise intelligence and collaboration platform for tracking the pharmaceutical product development lifecycle.
  • For example, the statistics below from an Ixia slide deck show that the cost of fixing a bug in production is 31X higher than fixing it at the build stage.
  • Finally, specify the tool usage, including whether it is open source or not and the number of users it can handle.

List the tools and software required to create and execute tests as well as technology for process automation. Describe in detail which tool is mandatory to complete which type of test. Finally, specify the tool usage, including whether it is open source or not and the number of users it can handle. This type of strategy is applied to ensure the code’s integrity after new changes. The method involves automation and aims at minimizing the risk of regression for product features.

Regression-Averse Test Strategy

One of the qualitative risk analysis technique is using Risk Matrix . This technique is used to determine the probability and impact of the risk. Because there are no formal test scripts, exploratory testing might simultaneously overlap the tests performed by different testers. Therefore, some scenarios might be tested twice or more, which is not a good use of their time.

Risk Based Testing

Exit Criteria – planned tests have been executed, coverage achieved, unresolved defects limited, remaining defects low, quality met. Now that we have understood what a test plan and a test strategy is, we can focus on the difference between a test plan and a test strategy. But before jumping off the deep end with the detailed differences, let’s first take a look at the key differences between the two. This includes questions like ‘what are the objectives of the testing process? A test plan varies from project to project, whereas a test strategy is used at an organizational level. A test plan is drafted by the test manager or test lead whereas the test strategy is drafted by the project manager.

There are many tools and best practices that can cut build time from hours to minutes. Consider TIA – execute per build only the relevant tests from your regression suite, where the code was changed. A regression testing strategy is your attempt to implement regression testing and make sure it is effective and providing value to the organization. However, software testing strategies are not incomplete without adequate reporting and analytics. WithBrowserStack Test Insights & Analytics, you can fill in the gaps.

Questions to ask before every Software Release

The Value Transformation staff have experience using scrum for embedded software projects as well as adaptations to the line management with great increases in efficacy. A short, non-exhaustive list of the areas upon which we can coach is found below. For the first situation, we are up against the delivery deadline and must cram some 50 pounds of testing in a 10-pound amount of time to mix metaphors. If we only have manual testing we have to decide what is most likely to cause serious problems to the customer and conduct that testing only so we can launch on time.

Measuring whether a specific test level or activity is done is part of the tester role. Whether the tester has enough knowledge and skill to perform the necessary tests. Test effort allocation based on risk assessment is the most efficient and effective way to minimize the residual risk upon release. Improved quality as all of the critical functions of the application are tested.

We are a team of technical experts with years of experience in software development and quality assurance services. Our customer-centric approach ensures smooth cooperation and delivers the desired definition of regression-averse testing results. This part is the meat of the entire document and describes testing procedures, roles and responsibilities of the team, various degrees of testing, as well as the change management process.

Last but not least, after each session, testers will gain more knowledge of how the system works in the areas where testers performed testing. Created by Mike Cohn, the agile testing pyramid helps testers understand how to implement automated testing. The bottom part of the pyramid represents types of testing that benefit most from automation. As you move up the hierarchy, exploratory testing—on the top of the pyramid— is non-automated.
