Agile development

Experienced QA professionals possess the skills and knowledge to identify potential issues and defects early in the development process. By involving QA outsourcing experts at an early stage, you can proactively address these issues, preventing costly post-release fixes and minimizing the impact on your product launch.

Software testing stages

Understanding the general process of software testing is essential for successful outsourcing. Here's an overview of the typical steps involved:

QA services outsourcing: testing stages

Requirements analysis

During the requirements analysis phase, the software testing services team reviews the project requirements to understand what needs to be tested. This step is critical because clear and comprehensive requirements form the foundation of effective testing. The team identifies key functionalities, performance criteria, and user expectations, ensuring all aspects of the software are covered.


The planning phase involves creating detailed test documentation that outlines the testing strategy, scope, objectives, resources, and schedule. This plan will describe the overall testing processes and serve as a roadmap. The test plan also includes risk assessment and mitigation strategies, ensuring potential issues are addressed proactively.

Creating test cases

Test cases are detailed, step-by-step instructions for testing specific functionalities of the software. These cases are designed to ensure all aspects of the application are tested thoroughly. The QA team writes test cases based on the requirements and uses the scenarios to cover all possible user interactions. Each test case includes input data, execution steps, and expected results, providing a clear guideline for testers.

Test environment setup

Setting up a test environment involves configuring hardware, software, and network conditions to mimic the production environment. Dedicated software testers ensure the test environment matches the end-user environment as closely as possible, including different operating systems, browsers, and devices. Proper environment setup helps in identifying issues that might occur in the production environment.

Test execution

During the test execution phase, the QA team performs the tests as outlined in the test plan. This includes usability testing based on the defined assessment criteria. This phase involves both manual and automated testing, depending on the project requirements. The team executes test cases, logs defects, and retests fixed issues. Test execution is iterative, with continuous feedback and adjustments to ensure comprehensive coverage and accuracy.

Defect tracking & fixing

Any defects or issues identified during testing are logged, tracked, and assigned to the development team for fixing. This phase includes re-testing fixed issues to ensure they are resolved appropriately. The QA team uses defect tracking tools to manage and prioritize issues, ensuring critical defects are addressed promptly. Regular status updates and defect reports keep all stakeholders informed about the testing progress and any outstanding issues.


Retesting involves verifying that previously identified defects have been successfully fixed without introducing new issues. This step ensures the software's stability and reliability. The QA team retests the fixed defects using the same test cases to confirm the resolution. Retesting is essential to ensure that fixes do not impact other parts of the application.

Regression testing

Regression testing checks that recent changes or fixes have not adversely affected existing functionalities. This step is crucial to maintaining overall software quality. The QA team selects a subset of test cases that cover critical functionalities and frequently used features. Regression testing ensures that new code changes do not introduce unexpected issues, maintaining the integrity of the software.

Test closure

The test closure phase involves summarizing and analyzing the testing activities and results. A final report is prepared, documenting the overall quality of the software and any remaining issues. The QA team conducts a test closure meeting to review the test coverage, defect trends, and key findings. Lessons learned and recommendations for future projects are also documented, providing valuable insights for continuous improvement.
