In 2012, the Knight Capital Group suffered a loss of USD 440 million and was pushed to the edge of bankruptcy because of a software bug. Investigations revealed that a change done to the power peg software automatically disabled the safety checks. This was believed to trigger 4 million erratic trades. It was found out that the software program with the new update was deployed in the live production platform without being tested for its functionality.
This incident highlights how the smallest of errors in software testing services can cause things to go wrong. Such errors may happen irrespective of whether you get the testing done through an in-house team or an outsourced agency. Therefore when you outsource your testing requirements, it is important to choose a partner who has a proven record of quality testing services. Here’s a look at how a quality assurance software testing company helps to optimize costs.
An experienced software testing services company will first sit with its client to understand the testing requirements. Based on this understanding the company will assign resources and tools. The software testing company and the client should mutually agree on all the testing activities. They will likewise enlist the browsers, devices, operating systems versions of the software that must be tested. It helps in investing money only on resources that are needed at the moment. Testing companies derive a clear answer on the following queries for better requirement analysis of their clients:
· What are the software testing priorities?
· What are the expectations from software testing?
· What are the test report delivery format and delivery timeline expectations?
· What is the expected mode of communication?
Testing at Early Development Phase
According to IBM, detection of bugs at the post-product release stage results in a 30x increase in expense. Any quality assurance software testing company tends to start testing a software product at the beginning of a software development life cycle. It helps in the early detection and resolution of bugs. A delay in detecting defects will necessitate product redesign, resulting in huge operational overheads. The process rerun will delay the product launch, thereby hampering enterprises’ revenue prospects.
A Test-driven Deployment Approach
Software testing services providers undertake a test-driven deployment approach. This approach involves writing unit tests before writing a code. These tests help specify the functionality and requirement of each code and avoid code redundancy.
Writing multiple units costs results in a higher test coverage extent. It increases the chance of bug detection at the early development phase, thereby reducing the testing effort and expenses required to fix bugs at the product launch stage.
Third-party vendors prefer automating visual regression testing implementing low code solutions to test the efficacy of an application’s user interface. This tool uses features like smart image comparison to analyze an application’s DOM structure, on-page elements. It handles automatic timeouts and supports user acceptance testing.
Using automated tools limits the product development time and negates the need to invest in testers for specific application testing functions.
Software testing companies write codes for automated tests that rerun the testing and retesting of a software-based on needs. This ability to reuse a single automated test scales up the test coverage while reducing dependency on manual labour to test the codebase.
Risk-based Testing Approach
This approach involves identifying the features that have the biggest influence on the software functionality and the highest possibility of malfunction. Third-party experts prioritize such risk elements and assign testing functions accordingly. Testing goals and strategies are based on such risk areas.
Such a focused testing approach further helps in the early detection of bugs. It helps avoid situations where enterprises have to invest and undo the software structure to reconfigure the malfunctioning features.
Though the primary reason for outsourcing software testing services lies in the cost-benefit, you must tread carefully to ensure the advantage does not turn into a nightmare. It, therefore, boils down to proper due diligence. Evaluate a vendor for their testing portfolio, years of standing, tester skillsets, and referrals. Only when you are doubly sure can you rope them in as your partner.
