It is very difficult to create any product without testing, as testing become important part of any business. Without testing, you cannot handover product to the customer. The main purpose of software testing is to compare expected result with actual result. In addition, software testing can help find the defect. If software tester starts testing at the beginning of the project, it is not that cheap, but if testing start at the end of the project, than it is very expensive to fix the defects. Because of this reasons, testers involve from the start of project. They start with the review of document. If they find any documentation or requirement error, it is easy to prevent, and it saves time and cost.
However, there are technical and non-technical skills, which would be advantage if testers have. In technical skills, testers must have knowledge of languages such as, Linux, C++, java, HTML or PHP. Moreover, any project require good amount of data that can help to create database and query. Therefore, database knowledge would be advantage as well. As a tester, you should also have knowledge of testing tools and techniques.
Moreover, along with the technical knowledge, testers should have knowledge in non-technical skills. Testers should have analytical skill, which means testers should know how to work with the complex project, and break that project into smaller pieces. This skill helps testers to create test cases and procedures. Also, testers should have communication skills, as testers have to write test cases, requirements, and talk to stakeholders. It is important that testers should know how to communicate with the client and stakeholders.
