What Skills Can Increase an API Tester's Salary?

Demanded Skills for the Role:

  • Analysis (Mentioned in 6.51% Job Postings): Analysis is the process of considering something carefully or using statistical methods in order to understand it or explain it.
  • Software Testing (Mentioned in 2.91% Job Postings): Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects), and verifying that the software product is fit for use. Software testing involves the execution of a software component or system component to evaluate one or more properties of interest. In general, these properties indicate the extent to which the component or system under test: meets the requirements that guided its design and development, responds correctly to all kinds of inputs, performs its functions within an acceptable time, it is sufficiently usable, can be installed and run in its intended environments, and achieves the general result its stakeholders desire.
  • Software Development (Mentioned in 2.27% Job Postings): Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products. Software can be developed for a variety of purposes, the three most common being to meet specific needs of a specific client/business (the case with custom software), to meet a perceived need of some set of potential users (the case with commercial and open source software), or for personal use (e.g. a scientist may write software to automate a mundane task). Embedded software development, that is, the development of embedded software, such as used for controlling consumer products, requires the development process to be integrated with the development of the controlled physical product. System software underlies applications and the programming process itself, and is often developed separately.
