A key area to focus on when considering a software testing company is its software testers. Today there exist two popular certifications, ISEB and ISTQB. Ensure that the software testers hold these certifications at the foundation level. Another factor about software testers is the amount of experience they have. Many software state that their testers have five years of I.T. experience. But reading between the lines means they have five years of knowledge anywhere in Information Technology. You should ask the software testing company how many years of professional software testing experience they have. Many software testing companies offer a wide range of software testing services. Caution should be used, though, as many of these companies will advertise these services but may not necessarily have the expertise to perform them. The types of software testing services that any professional company should offer are:
Test Case Creation
Clients are involved in every stage of test case development through a test case review process. This top-rated service typically involves creating detailed test cases for the project under test. Due to their high quality can be reused on future projects and form a high-quality test documentation asset. Good testers will accumulate all the required information to produce the test cases, typically from design documentation, requirements, and developer interviews. Once the information has been analyzed, a software tester will create a sophisticated Excel spreadsheet that includes test cases, results sheets, environment setup, version details, etc.
Today’s Typical software products include large amounts of critical functionality and complex features; added to this, significant time pressure to get the product released makes functional testing one of the most important stages of any software development. A software tester’s manual applicable testing techniques have been proven to be highly effective at determining whether or not the functionality works. Versatile software testers can work from their own created test cases or use any pre-existing test cases you may already have. Good software testers readily use ad-hoc techniques when executing any tests to expand the test coverage. The aim during functional testing is to highlight any issues as early as possible so the developers can resolve them. This can effectively reduce the development costs for your company.

Usability Testing can be used to ensure your software meets the end-user’s needs. Not only will usability testing detect errors, but it will also detect navigational issues, language issues, workflow experience, etc. Good software testers put themselves into the mindset of the end-user and will report on the ‘look & feel of the software under test. Good software testers often build test cases based on real end-user scenarios or business cases to ensure the software is tested similarly to how the real end-users will use the software. This type of software testing has been proven to increase the ROI of software developments by enhancing the end-user experience and potentially increasing product sales. As usability testing ensures that the end-user experience is appreciated, we perform this testing manually.
Regression testing is a surprisingly often overlooked area of software testing. This is often due to the assumption that the software is ready for release when new functionality is working correctly. However, more often than not, additional issues that affect existing functionality have been introduced. Software testers have the knowledge and experience to identify existing test cases suitable for regression. Regression test cases are commonly functional tests reused regularly throughout software development to ensure that the expected results remain consistent, thus providing confidence that nothing has been adversely affected by the change.
The end-user or customer typically drives acceptance testing. The customer normally executes acceptance test cases before accepting the product. But these test cases are commonly given to the software developers to ensure their product meets the level of acceptance before the of development. Software testers can execute these test cases to highlight any issues to the development team as early as possible. Software testers can also derive expected acceptance test cases from your customer requirements. On a smaller scale, our software testers can also derive smoke tests from acting as acceptance tests during stages of the software development life cycle.
System testing of software is testing conducted on a complete, integrated system to evaluate its compliance with its specified requirements. Good software testers treat System testing as an investigatory testing phase, where the focus is to have almost a destructive attitude. They will aim to test the design, the behavior, and even the believed expectations of the customer. Software testers will be tested up to and beyond the bounds defined in the software requirements specification. This is a test that if a failure occurs, it is handled correctly by the software with as little impact on the customer as possible.
