Levels of software testing

The levels of testing in the software development process, such as unit testing, integration testing, system testing and acceptance testing.

sector-specific

Levels of software testing is an essential knowledge of the following occupations:

ICT test analyst: ICT test analysts work in testing environments, assessing products, checking for quality and accuracy, or creating tests scripts. They design tests which are then implemented by testers.
Software tester: Software testers perform software tests. They may also plan and design them. They may also debug and repair software although this mainly corresponds to designers and developers. They ensure that applications function properly before delivering them to internal and external clients.
Digital games tester: Digital games testers review and test various genres of digital games by playing them in order to find bugs and glitches within the game’s functionality or graphics. They may evaluate the capacity of attraction and playability of games. They may also debug the games themselves.
Aviation ground systems engineer: Aviation ground systems engineers are in charge of supervising the maintenance of the equipment of the airport, for example, the visual aids, airport electrical systems, luggage systems, security systems, pavements, drainage, maintenance of unpaved areas and equipment and vehicles.
ICT accessibility tester: ICT accessibility testers evaluate websites, software applications, systems or user interface components with regards to friendliness, operability of the navigation and visibility to all types of users, especially including those with special needs or disabilities.
ICT system tester: ICT system testers perform testing activities and some test planning activities. They may also debug and repair ICT systems and components although this mainly corresponds to designers and developers. They ensure that all systems and components function properly before delivering them to internal and external clients.
ICT usability tester: ICT usability testers ensure compliance with requirements and strive for optimal usability within the software engineering cycle phases (analysis, design, implementation, and deployment). They also work closely with users (analysts) to research for and document user profiles, analyse tasks, workflows, and user scenarios.
ICT integration tester: ICT integration testers perform tests in groups of system components, units or even applications. They group them in larger aggregates and apply integration test plans on them. They oversee the complexity of relations between different components.
ICT quality assurance manager: ICT quality assurance managers establish and operate an ICT quality approach through quality management systems, in compliance with internal and external standards and the organisation’s culture. They ensure that the management controls are correctly implemented to safeguard asset, data integrity and operations. They focus on the achievement of quality goals, including the maintenance of the external certification according to quality standards and monitor statistics to forecast quality outcomes.
ICT system analyst: ICT system analysts specify the system needs to meet the end user requirements. They analyse system functions in order to define their goals or purposes and to discover operations and procedures for accomplishing them most efficiently. They also design new IT solutions to improve business efficiency and productivity, produce outline designs and estimate costs of new systems, specify the operations the system will perform, and the way data will be viewed by the end user. They present the design to the users and work closely with the users to implement the solution.

Levels of software testing is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Software analyst: Software analysts elicit and prioritise user requirements, produce and document software specifications, test their application, and review them during software development. They act as the interface between the software users and the software development team.
ICT disaster recovery analyst: ICT disaster recovery analysts develop, maintain, and implement ICT continuity and disaster recovery strategies and solutions. They support the technical teams, assess the risks, design and develop procedures, documentation and strategies for disaster recovery in order for business functions to continue and recover with a minimal loss of data. They also coordinate the system backups tests and validations.
Ethical hacker: Ethical hackers perform security vulnerability assessments and penetration tests in accordance with industry-accepted methods and protocols. They analyse systems for potential vulnerabilities that may result from improper system configuration, hardware or software flaws, or operational weaknesses.
ICT security manager: ICT security managers propose and implement necessary security updates. They advise, support, inform and provide training and security awareness and take direct action on all or part of a network or system.
