Description: Pre-execution in Travis CI refers to a set of tasks or checks that are carried out before the execution of a build or deployment begins. This process is crucial to ensure that the build environment is properly configured and that all necessary dependencies are available. During the pre-execution phase, various checks can be performed, such as validating project configuration, verifying code integrity, and installing required libraries or tools. These tasks help identify potential issues before the build process starts, which can save time and resources by avoiding failures in later stages. Pre-execution may also include running test scripts or checking that the code adheres to style and quality standards defined by the development team. In summary, pre-execution is a fundamental step in the continuous integration workflow, as it lays the groundwork for a successful and efficient build process.
