The Apache JMeter is an open source load testing tool developed by the Apache Foundation that can be used to test performance both on static and dynamic resources. It can be used to simulate a heavy load on a server and also some functional testing. JMeter has an open architecture that can be extended with plugins.
Software Testing Tools: Unit Testing Tools, Functional Testing Tools, Load Testing Tools
Test management is defined by Wikipedia a part of the software testing process that includes the planning of tests, their execution and the storage and analysis of the tests results. This is achieved also by the integration with requirements management tools, functional software testing tools like Selenium or Cucumber, continuous integration tools like Jenkins or TeamCity, bug tracking tools like Bugzilla or Mantis, project management tools like Trello Redmine or JIRA.
Behavior-Driven Development (BDD) is an Agile approach that mixes requirement gathering, documentation and acceptance testing. You write human-readable sentences describing the features of your application and how they should work. Then you implement this behavior using a tool that produces automated acceptance tests to verify that the feature is implemented correctly. Open source .NET BDD tools like SpecFlow are used to store the requirements as live documentation and to perform functional or acceptance tests.
Database testing is one of the areas that might have the smaller number of open source tools. The programming languages have many xUnit tools and mocking frameworks, but this is not the case for databases. This article provides a list of open source tools that can be used to perform unit, load and security testing on several relational (MySQL, Oracle, SQLServer, etc.) and NoSQL databases.
Even if Windows might be the most used operating system in software development organizations, it doesn’t mean that you cannot use a computer working with Mac OS to perform functional testing. This article provides a list of open source functional testing tools that work on Mac OS.
SpecFlow is an open source Behavior-Driven Development (BDD) tool for .NET. SpecFlow uses the official Gherkin parser and supports the .NET framework, Xamarin and Mono. You can use SpecFlow to define, manage and automatically execute human-readable acceptance tests in .NET projects. Writing easily understandable tests is a cornerstone of the BDD paradigm and also helps build up a living documentation of your system. Anton Angelov has created a series of articles dedicated to Specflow that starts with an introduction tutorial.
In most of your software testing activities, you need data. Sometimes you can rely on a small sample, but if you want to perform some load testing or if you want to test a features that needs to produce a multi-page invoice, then you start to need more than just two or three occurrences. Test data generators are tools that can help you in this task with the automatic generation of hundreds or thousands of customers, products or accounts items with different attributes for their id, email, name, etc.
