GitHub’s major competitor is Bitbucket, an Atlassian product that has deep integrations with JIRA, Confluence, and Trello. For up to 10 users, Bitbucket is cheaper. When you hit 10+, it’s more expensive but may work out as cheaper for large enterprises. Also, if your company is looking to spark interest in the open source community, there’s no bigger audience than GitHub’s.
Citrus Framework is an automated testing tool with integration framework for messaging protocols and data formats. HTTP, REST, JMS and SOAP can all be tested within the Citrus Framework, outside of broader scope functional automated testing tools such as Selenium. Citrus will identify whether the program is appropriately dispatching communications and whether the results are as expected. It can also be integrated with Selenium if another front-end functionality testing has to be automated. Thus, this is a specific tool that is designed to automate and repeat tests that will validate exchanged messages.
The ROI on automation tests varies depending on several factors. Some tests are difficult to develop because of technology constraints. For example, testing frameworks may not support test cases that run across several browser sessions or across different devices. Other tests may not need to be run frequently. For example, it might be more cost-effective to occasionally and manually test a use case for a rarely used feature, rather than invest the time to develop and maintain an automated test that runs after each nightly build. Each organization will make its considerations according to its own priorities, but it's always important to consider the ROI you'll get by automating your tests.
This article uses the term “tester” to refer to the person involved in testing software with automation tools. It is not meant to distinguish by job title or technical proficiency. Jim Hazen describes himself as a hybrid, or “technical tester,” because he can write test scripts and develop what he refers to as “testware.” The trend is to hire for multiple skillsets, but that does not mean the non-technical stakeholders involved in software development don’t benefit from automation testing.
