Cloud applications typically involve several components that interact through an API that exchanges data in either the XML or JavaScript Object Notation (JSON) formats. This article from Shalini Gilra, Prem Prakash and Tom Tuohy discusses techniques for using the open source tool Apache JMeter to perform functional, performance and reliability testing of Cloud applications that use RESTful web APIs and JSON.
Xcode is the complete toolset developed by Apple for building Mac apps and iOS apps. In these two part article, Charlie Fulton proposes a tutorial to start performing unit tests for apps developed with Xcode in a continuous integration context.
This article provides a comparison between HP QuickTest Professional (QTP) and Selenium. They are popular test automation tools that are used for functional and regression testing. The purpose of this comparison is not to say which is better tool, but it consists of comparison of tool based on different criteria like supported O/S, browser, object spy, object repository, license cost etc. This article is targeted for readers having prior working knowledge of automation approach and at least one automation tool.
In my previous column PHP Unit Testing with PHPUnit,I showed how to set up PHPUnit and how to run a few simple tests. You should be able to test any function or method now that doesn’t rely on making calls out to other methods or functions – which is of course very few, as most applications are a complex combination of methods and, in PHP’s case, functions.
Root Cause Analysis (RCA) is an approach used in software testing to identify the root causes of defects or problems and address them instead of treating the symptoms. It’s a process that grew out of accident investigations to become a standard feature of hardware engineering. If something is broken, instead of just fixing it at the point of discovery, let’s investigate and try to fix the underlying cause at the point of origin. This principle is applicable for software development and software testing, so much so, that it could have been developed to deal with software defects.
Distributed software development teams and distributed software testing are here to stay. In this article, Lisa Crispin asks “How do we get quality software in these situations?” and proposes some hints on how to get good results when you perform software testing with distributed teams.
Automating tests is an investment that is valuable as long as the investment is not too great. As such investing in automated testing tools can be great or bad depending on if your company really needs to automate. We want to get to the payback more quickly. The true investment is not only the cost of creating and maintaining automated tests. Watir is a family of libraries for testing web applications. Watir reduces the cost of creating automated tests that are maintainable. If we spend too much time fixing and debugging, we will never get the new features created, or we will abandon the automated tests temporarily.
