Whitepaper: Top Testing Tips for .NET

Unit testing is not enough to move the needle on Microsoft .NET testing automation. You need dynamic and static code analysis to discover bugs and security vulnerabilities.

Learn how to build a comprehensive testing strategy for your .NET application with Parasoft dotTEST.

Key takeaways:
  • The criticality of unit testing
  • Benefits of automated unit testing
  • How Parasoft supports TDD
  • How static analysis complements automated unit testing
  • How Parasoft automates key aspects of software testing
  • Software complexity is constantly increasing, while at the same time businesses are pushing to maximize their profitability in the in the shortest time possible.
  • As a result, creating new systems often involves using legacy modules that are migrated from older systems in order to minimize software testing and quicken product delivery. It also allows developers to apply quick fixes rather than follow design patterns.
  • These factors can have a negative impact on the product and increase the risk of finding defects in the later stages of the development process. Subsequently, software testing is essential.
  • Dynamic analysis is critical in supporting unit testing to detect runtime errors missed by manual testing. Collection, storage, and analysis of results is also critical to support large, team-based projects. Another critical aspect of automated testing is static code analysis, to discover bugs and security vulnerabilities that unit testing can miss.
  • Parasoft dotTEST lets you take advantage of all these capabilities to make your code more reliable and efficient.

Parasoft dotTEST is integrated with Visual Studio, the leading IDE for developing .NET applications. Visual Studio has a longstanding history as being the best IDE in the .NET world. It makes writing code easier thanks to its IntelliSense features, good refactoring capabilities, quick fixes and other features that are useful for code editing.

It also provides several testing capabilities, including the ability to run static analysis and execute unit tests. All these factors make Visual Studio a very productive IDE; however, despite its range of useful functionalities, Visual Studio only scratches the surface on helping eliminate code defects. Parasoft dotTEST can help make a significant difference by minimizing the number of defects in the early stages of the development process, which helps you avoid the cost of fixing them in the later stages.

It’s common for development teams to lack the motivation to write unit tests or write insufficient tests because everyone’s on a tight schedule and it’s simply not a priority. But unit testing is critical, and development teams need adequate time and a supportive environment to reap its benefits, which include:

  • Easy debugging of detected defects
  • Saving time and effort of fixing other issues detected later in development
  • Fewer bugs in system and acceptance testing
  • Better understanding of requirements, leading to more robust design and implementation
  • Easily reusable test code
  • Ability to test early in the lifecycle
  • Faster responses to requirement changes and bug reports
  • Living documentation of the system

TDD helps developers understand requirements as they’re creating tests before implementation. TDD can be used with any testing framework for .NET.

When it comes to .NET, there are two main frameworks for testing: NUnit and MSTest. Parasoft dotTEST is compatible with both, with the ability to generate rich test reports and send results to Parasoft DTP, a sophisticated reporting and analytics tool in the Parasoft testing suite.

But testing framework capabilities aren’t enough. Mocking and stubbing frameworks are also key to ensuring proper test isolation. dotTEST provides an easy way to automate running tests efficiently. Along with Parasoft DTP, it can store results, show historical data trends, complete test history and detect unstable tests.

Static analysis allows you to identify possible defects and code early. No unit test infrastructure is needed since code is analyzed statically. Using static analysis, you can reduce time required to fix defects and avoid high costs of discovering defects late in the development process.

Static analysis is also necessary for meeting certain quality objectives, especially in the case of safety-critical computer systems like medical, avionic or automotive software. These systems require traceability compliance. Parasoft dotTEST and DTP cover key aspects of traceability compliance and allow easily correlation of coverage data with the test and requirement being tested.

Coding standards are also helpful in avoiding defects and improving software quality, like MISRA C, OWASP, CWE-SANS and more. Parasoft dotTEST ships with ready-to-use test configurations that cover different common coding standards.
