Tutorials and resources on how to apply unit testing in software testing
The new Visual Studio 2012 tries to improve the developer unit testing experience, particularly for agile teams. The entire unit testing framework has been made extensible, which will allow you to use testing frameworks such as xUnit.net and NUnit in addition to the unit testing framework built into Visual Studio. This talk presents the history of unit testing in Visual Studio and then takes you through the product, showing off the new unit testing features.
This blog post explains how to perform unit testing of MySQL stored procedures. A stored routine is a set of SQL statements that can be stored in the server. Once this has been done, clients don’t need to keep reissuing the individual statements but can refer to the stored routine instead. To perform unit testing on stored procedures, you can use utMySQL, an open source unit test framework for MySQL stored procedures. This post provides a step by step process on how to create the test code in utMySQL which is also a stored procedure, run it and verify the results.
This blog post by Stuart Gunter shares some best practices to perform unit testing on Spring MVC views. The concept follows a BDD style to write unit tests that leverages the MVC pattern in much the same way as the real application, but exploits the power of standard unit testing practices like mocking, assertions and verification. This is achieved with the open source software testing tool TestNG and using the infrastructure provided by Spring through its integration testing features in order to execute the unit test. The post shows the code, also available on GitHub, used to do this. It also explains the design decisions that supports this approach.
This is a series of three posts by Nick Olson about the topic of unit testing your code your when you are writing a javascript client application with a .NET backend. The first post is an introduction that defines the context and presents the tools that will be used. The second post provides the code to test the javascript using KnockoutJS and Qunit. The third post explains how see the javascript unit tests results when you are inside Visual Studio. This is achieved using a browser automation tool walled Watin and a data-driven unit test in C#.
PL/SQL is an Oracle’s procedural extension to SQL that allow to code the stored procedures in Oracle database. In this blog post, Nick Giles explains how he uses DbUnit to perform unit testing tor the stored procedures in Oracle. DbUnit is a JUnit extension (also usable with Ant) targeted at database-driven projects that, among other things, puts your database into a known state between test runs. In his solution Initial data and the expected output state of the tables containing the aggregated values are specified separately in two simple XML files. These are then referenced in a test method in a Java class along with the command to run the pre-calculation stored procedure. It worked so well that he could adopt a Test-Driven Development approach for his project.
Evan Farrer to test the frequently cited claim by proponents of dynamically typed programming languages that static typing was not needed for detecting bugs in programs. In his blog post, he explains why unit testing isn’t enough and you need static typing too.
This article shows how concepts and axioms can be expressed in standard C++ 2011, and explore Axiom-based testing is a technique for testing generic code in a generic way, based on algebraic specification. This article explores how you can specify graph transformation-based rules for a classical problem of transforming from UML sequence diagrams to state machines. The specification of the transformation rules is based on the concrete syntax of sequence diagrams and state machines. It introduces tailored transformation support for sequence diagrams and a novel graphical operator to match and transform combined fragments.
