5 Learnings from writing 1.000 test cases as a c# test automation expert
In my three years as a consultant in software test automation for c#, I’ve written a lot of test cases. These are my top 5 learnings. 1. A failing test doesn’t necessarily mean that you found a bug in the

Automated Frontend Tests
We now look at which tools can be used to support the creation of automated test cases. For executing test cases on a frontend, the created code actions must be converted to be executed on the frontend and mapped to

Stages of Test Automation
In this article, we introduce three different stages of Test Automation, as originally proposed by Mike Cohn [1], and give characteristics of test cases in each stage. As naming and definition of the individual stages differ in the literature, we

Models – theory vs. reality
In a previous article, I have discussed the power of models in software engineering. In theory, using models solves the most fundamental problem in software engineering: the communication between business (e.g. client, project manager, business developer) and engineering (e.g. developers,

Barriers and limits in test automation
The potential of Test Automation is huge. Dependencies to requirement specifications change requests and project deadlines significantly impact the success of Test Automation. Insufficient fulfilment of prerequisites often provides huge barriers to the automated execution of test cases in software

Benefits of Test Automation
What is Test Automation? Software often aims at providing automation to manual tasks. However, in classic approaches, testing developed software is still done manually. Therefore, the basic idea of test automation is to “write programs that test programs”. As a

Define once, reuse always – the power of mutants in Software Testing
When defining test cases, a lot of manual effort is spent on repeatedly deriving tests based on predefined methods (e.g. Boundary Value Analysis), with the aim to maximize coverage of created test suites. As white-box evaluation metrics, such as code

Challenges in modern software testing
Software testing is an important and critical factor in the whole development process. The challenges in modern software testing are constantly growing. Trends like agile software practices and DevOPs lead to reduced release cycles. This affects not only digital leaders

Testing as a crucial part of software development
Testing is an important activity in software development. It aims at finding incorrect implementation of requirements before software is shipped and potentially tremendous results occur. Prominent examples of such errors are the crash of the Ariane 5 skyrocket [1], the

Metamorphic Testing – What matters when defining test cases?
In software testing, test cases are currently defined by specifying expected output for a particular input. If this expected output does not match the actual output of a tested system, a fault is detected. However, this usually requires the tedious
