A systems test engineer is responsible for checking software applications for defects before they are released to consumers. They work in a company’s testing department and use automation software to test applications. They must understand computer programming and create an environment that resembles the system configuration used by consumers. A good test cycle includes positive and negative testing.
Computer software manufacturing is a company based on developing software applications for consumers. A systems test engineer is an individual responsible for checking software applications for defects. He normally tests an application to ensure that the system works as intended before it is released to consumers in the market.
Historically, system testing has been completed by the software engineers who originally created the application. This practice proved to be inefficient because the developers were intimately familiar with the software and typically had no system defects. In recent decades, systems testing has become a discipline in computer science.
Quality software products require hours of rigorous testing. The systems test engineer is the quality control specialist of a software development organization. He usually has the authority to reject defective software. He usually works in a company’s testing department and is considered the last quality checkpoint before production.
To become a systems test engineer, an individual must understand the basic principles of computer programming. He should have some college education with an emphasis on computer science. Most large companies have a dedicated testing team specializing in quality assurance processes. This team typically includes test managers, engineers, technical writers, and automation testers.
Today there are many automated software applications that manage defects found by the systems test engineer. This software is a basic scorecard of issues documented by the test team. The test engineer is responsible for tracking, managing, and reporting all defects found in the software application. This documentation process is typically performed with each software build and test cycle.
Testing computer software is usually done in an independent testing environment. This environment is managed and configured by the systems test engineer. He is responsible for creating an environment that resembles the system configuration that will be used by consumers. The test engineer creates special test scripts designed to test all facets of the application.
A good test cycle is one based on positive and negative test samples. Positive testing is a process in which a system is tested with good data that follows a defined business process. Negative testing is a form of testing that ensures that error handling works correctly with bad data. This is considered a more detailed testing process because the tester is trying to crack the system.
Most systems test engineers use automation software to test applications. This software is based on test scripts, which perform the actual testing. Automation software is a more accurate method of testing that can be used for regression testing an application in the future.
