Running Automated Tests in Parallel (Part 1)` provides insights into maximizing the value of automated functional tests by providing results quickly to developers. Typically, test suites can take many hours to run due to sequential execution and data dependence. To overcome this, batches of tests can be created and run on separate machines with their own instances of the application under test and database, utilizing spare hardware or cloud computing resources. Continuous Integration servers like Jenkins and Bamboo enable easy setup for running builds on multiple computers, known as Slaves or Agents, allowing grouping of tests into categories or groups that can then be executed in parallel. This enables faster feedback to developers, reducing the likelihood of issues remaining unaddressed.
