Methodologies

There are different types of methodologies used in the field of software testing and quality assurance. At (COMPANY NAME) different sets of test cases and testing strategies are prepared, all of which are aimed at achieving one common goal - removing bugs and errors from the code, and making the software error-free, and capable of providing accurate and optimum output for our clients.

Waterfall Model (Linear Sequential Life Cycle Model)

Waterfall is one of the oldest models that can be used not only for the software testing needs. Its basic principle is a sequential order of steps. It means that we can move to the next step of development or testing process only after the previous step was completed successfully.

This model is applicable for small projects only in case if all requirements are clearly defined.

Advantages of Waterfall Methodology

  • Cost-effectiveness
  • Waterfall model is simple to implement,and the amount of resources required for it are minimal.
  • All the testing and modification is done is the same phase, chances of defect multiplication reduced
  • The project with short span time can be developed with this model in better quality.

Agile Methodology

Agile Methodology uses iteration approach. We implement Agile methodology to be able to respond and adapt smoothly to all changes that emerge during the software development and testing process. When using agile methodology, your software development process will be divided into numerous short cycles or iterations that help to minimize the risks.

As a result, your software development process will consist of several releases, each of which will be built on a previous version. Testing process is carried out for each release.

Agile methodology is based on the following principles:

  • Face-to-face communication is a must.
  • Response to changes is more important than strict compliance with a plan.
  • Interactions between individuals are more important than processes and tools.
  • Changes are always welcome.

Advantages of Agile Methodology

  • Immediate user feedback: The emphasis on getting shippable products into the hands of users means the project is guided by the market. This reduces the risk of building an app that nobody wants while increasing the chances you'll find that killer feature that will sell your product earlier in the project life cycle.
  • Fast, high-quality delivery: TDD at each iteration leads to fewer bugs and higher-quality releases. A solid foundation leads to quicker, higher-quality releases with successive iterations.
  • Teamwork: Agile methodologies place an emphasis on frequent communication and face-to-face interactions. Teams work together, benefit from pair programming, and interface daily with business development.
  • Adaptability: The short development cycles of the iterative design process give the project the flexibility to pivot when it needs to

Scrum

A part of Agile methodology, an iterative and incremental framework for managing software application development. According to the Scrum principles QA team has to perform the following tasks:

  • Participate in Sprint/Release planning;
  • Support in Unit Testing;
  • Test User Stories when completed;
  • Collaborate with customer and product owner to define the acceptance criteria;
  • Provide automation testing;

V-Model (Verification and Validation model)

Just like the Waterfall Model, V-shaped life cycle model is based on the direct sequence of steps. The main difference between these methodologies is that testing is planned in parallel with the corresponding development phase. According to this software testing methodology, the process begins when requirements are ready, so we can perform static testing - verification and review, that helps to prevent possible defects on the latest stages. A corresponding test plan is created for each of the software development levels, which determines the expected results as well as entry and exit criteria of the product.

A The phases of the V-model are changeable but usually they include the following:

  • Requirements phase. Acceptance testing is related to this phase. Its main purpose is to evaluate if the system is ready for the final usage.
  • High-Level Design phase relates to System testing and includes evaluation of the compliance of specified requirements to the integrated system.
  • The Detailed Design phase is parallel to the Integration testing that checks the interactions between different system components.
  • After the Coding stage begins another necessary phase - Unit testing. It's important to make sure that behavior of individual parts and components of your software is correct and meets the requirements.

Test Case coverage

(Company Name)- offers our customers a wide variety of test case services. Rich experience in fields of QA, QC and Software testing have carved us into mature professionals, fully aware of what value decent quality provides businesses with. Test cases are core of any QA process as they define what functionality is supposed to work and how it should operate according to business requirements. Test cases allow clarity throughout automation and manual testing processes to ensure maximum efficiency and eliminate most possible risks of end-product failure.

    Ways to Measure Test Coverage

  • Number of ways test coverage is done
  • Test coverage by feature
  • Test coverage by GUI icon
  • Test coverage by scenario
  • Test coverage by transition
  • Test coverage by structure.

Test Execution

Simply writing a test case is not enough. It must be properly run using automation tools or manually. Both these activities require skill, attention and precision from testers. 10+ years of experience allow our experts to be the kind of people you really want to be involved in testing of your products: their scrupulous attitude, critical thinking and deep understanding of all testing processes have already left clients like Blackberry, Canadian Western Bank and others more than satisfied with achieved quality.

Defect management

During all activities in software development, defects can be found. A defect is an observed difference between the expectation or prediction and the actual outcome of a test. Many people see the finding of defects as the purpose of testing. While it should be clear that the purpose of testing is much more ( the provision of information and advice concerning risks and quality) the fact remains that finding defects is one of the most important activities of testing. That is why defects are often recorded and tracked. This way the defect can't get lost or forgotten.

    The purpose of defect management may vary. The purpose of defect management for your project or organisation can be:

  • Operational support for solving and retesting defects;
  • Give input for status and progress reports;
  • Give input for the release advice.
  • Each defect can also be the trigger for development process improvement - what was the reason that the defect occured and can we prevent the defect from occuring in the future

    Our team has hands on experience in all industry standard tools such as:

  • HP Quality Centre/ALM
  • JIRA
  • Microsoft TFS
  • Microsoft MTM
  • IBM Rational Clear Quest
