A typical day for a tester: the responsibilities and the skills required
What a tester does at a tech company
The tester is a key figure in assuring software quality. Their job is to check products for defects, help improve them and make sure they are comfortable to use. In this section we go through a tester's main responsibilities: analysing requirements, writing test plans and running test scenarios. Testers also take an active part in the decision to release a product, offering their expertise on the problems found and the possible fixes.
Why communication matters in testing
Communication is the cornerstone of a tester's work. Defect reports and feedback to the development team are what let problems be fixed promptly and keep software quality high. In this section we discuss how testers coordinate their work with developers and the rest of the team. Communicating effectively also means being able to explain technical detail to non-specialists such as project managers or clients.
The testing process and the main types of test
Software testing is an involved process taking in a great many kinds of test: functional, load, integration, regression and so on. In this section we go through each of them and explain how they help testers find and fix defects. We also look at the different approaches — black box, grey box and white box — and describe how to pick the most suitable one for a particular project.
The skills and competencies of a good tester
A tester's skills and competencies matter a great deal to their professional growth and effectiveness. In this section we go through the key ones: an analytical turn of mind, a knowledge of programming languages and the ability to work with a range of testing tools. Testers also need to adapt to shifting market requirements, develop their teamwork and manage their time well.
The role of automation in testing
Test automation is the practice of using purpose-built tools and technologies to run tests and compare expected results against actual ones. In this section we look at what automation brings: speed, greater accuracy and less scope for human error. We also discuss popular automation tools such as Selenium and JUnit and how they fit into the development process. Automation can also free testers to concentrate on the harder, more critical work of assuring quality.
How Agile and DevOps change a tester's work
Agile and DevOps aim to improve how software is built and shipped, and testers play a key role in making both work. In this section we look at how testers work with Agile teams and how their role and responsibilities change under DevOps practice. Testers have to be flexible and respond quickly to change, because both Agile and DevOps put the emphasis on a short development cycle and continuous improvement.
Continuous learning and development
The tech market never stops changing, and testers have to keep improving their skills to stay competitive. In this section we look at why professional development matters, discuss the popular certifications and courses, and offer advice on studying independently. To keep up with new technology and tooling, testers should take part regularly in conferences, webinars and workshops and follow the news and writing in the field.
A typical day for a tester is a combination of varied tasks demanding broad knowledge and a varied set of skills. Testers play a key role in assuring software quality, working closely with developers, managers and everyone else involved in building and shipping a product. Active professional development, adapting to new methodologies and taking up automation will help testers meet the challenges of modern tech and build a successful career.
