  • Software Testing & End-to-End QA Services

Deliver Flawless System Functionality & Beat Your Competitors

Functional Testing validates the software system according to the functional requirements. It involves black box testing and is not related to the source code of the application. This test checks the user interface, APIs, database, security, client/server communication and other functionality of the tested application. The test can be done manually or using automation. Our Functional Testing Services focuses on ensuring the functionality of a software application before it enters the production phase. It reviews every aspect of a piece of software to make sure that it works correctly.

Process of functional testing that we perform are:

  • Gather functional requirements and design specifications
  • Create a functional test plan and test cases
  • Execute test plan
  • Log defects
  • Retest after issues have been fixed

Assures The Existing Functionality After The Introduction Of New Challenges

The world of software dynamics is changing rapidly. Constant changes and improvements are necessary for the success of any application or software. However, whenever a developer modifies or makes changes to software, there are high chances of having unexpected results. Therefore, Regression Testing is done to verify that a modification in coding does not impact the existing functionality of the product. The main purpose is to make sure the product works fine with new functionality, bug fixes or any change in the existing feature.

Our approach includes:

  • Outlines of the requirements vs. test cases
  • Dependency analysis performed between test cases and requirements
  • Issues between the current release and previous release
  • Release specific regression test pack
  • Risk-based analysis
  • Continuous pruning by removing the test cases that are no longer needed & add additional ones.

Benefits of Regression Testing are:

  • It can be easily automated which saves time & cost of testing.
  • Ensures the data integrity & validation after the errors have been fixed.
  • It helps to maintain the quality of the source code.
  • It is a beneficial option for applications that require continuous modifications.
  • Allows timely detection of errors & bugs.
  • Assists with quality-oriented product development with required modifications.

Regression testing is a reliable way to ensure that the applications remain defect-free even after frequent changes.

Ensure your System is Robust and Reliable enough to handle Peak Loads

Performance testing is the process of determining the speed, responsiveness and stability of the application or software program under a specific workload and ensures high-quality performance. It exposes different aspects of the software that need to be improved before your products get launched in the market.

Our approach includes:

  • Analyze the backend structure of the application
  • Familiarization with your process
  • Create a scope of API requests for testing
  • Run API calls in 100/1000/10000 threads at the same time
  • Save and analyze test run results
  • Collect performance metrics

Performance Testing Types We Perform:

  • Load testing- Evaluates software behaviour under a specific expected load
  • Stress testing- Identifies the upper limits of software capacity
  • Scalability testing- Measures software capability under increased processing power and architecture changes
  • Stability testing- Determines the effect of configuration changes on the system's performance and behaviour
  • Volume testing- Evaluates software productivity under an increasing volume of stored and processed data
  • Configuration testing- Verifies the operation of software with multiple software and hardware configurations


  • Validate the fundamental features of the software.
  • Measure the speed, accuracy and stability of the software.
  • Performance testing allows you to keep your users happy.
  • Identify discrepancies and resolve issues.
  • Improve optimisation and load capability.

Singsys has a team of certified ethical hackers. We ensure that your application is protected from any vulnerabilities, and meets the security essentials like confidentiality, authorization, authentication, availability and integrity.

Maximize user satisfaction.

Helping you deliver best User Interfaces (UI) & User Experience (UX).

Usability testing along with user acceptance testing evaluates if the product meets user expectations and how easy it is to use. Poor usability can affect your customer loyalty, directly affecting sales and brand reputation. The application should be easy to use, navigate and should meet customers’ expectations. This testing helps you identify all the usability issues before the application is launched, providing an intuitive user experience to the end-users.

Need for Usability Testing

  • Easy accessibility of the website by the end-users
  • Difficulties or errors customer could face while using the website
  • Bad user experience can result in losing the customer.
