App Testing

Use our professional app testing to make sure your mobile applications are accepted by your users.

Because usability and performance are decisive criteria for the acceptance of mobile applications. Especially in the consumer sector, apps that do not meet the users’ user-friendliness and performance requirements are quickly uninstalled. But also in the B2B environment, the usage intensity of an application depends on the user experience. Particularly in enterprise applications, the range of functions and efficient operation are critical to success.

Important for the success of a mobile application is therefore not only the professional app development, but also the testing of mobile apps. An app should under no circumstances only before a release, but continuously on, inter alia, on functionality, usability, compatibility and performance

Manual Test for Mobile Applications

In addition to automated app testing using emulators and simulators, manual testing offers many advantages. Mobile solutions offer added value through the use of device-specific functions such as temperature sensors, gyroscope, height measurement and geolocation data. However, these features can only be checked for their actual functionality by manual testing. In addition, different mobile networks have a significant influence on the performance and thus the usability of mobile applications.

  • Component test: test individual modules, programs, objects or classes with regard to functional and nun-functonal aspects
  • Integration test: Ensuring the interface functionality
  • System test: Functional and non-functional testing of the entire system based on technical specifications and defined use cases
  • Acceptance test: Usability review from the user’s perspective
  • Exploratory test: Intuitive test case determination by our experienced ISTQB certified testers
  • Static test: static analysis, reviews, walkthroughs or inspections
  • Regression test: repeated testing after modification or debugging
  • Crowdtesting: Comprehensive testing of various operating systems and device types with almost complete variant coverage
  • UX-Review according to DIN EN ISO 9241-110 by our certified UX experts
