Build information files contain version and build information that is used for execution runs. The build information files are typically stored and searched for on the execution server that is executing the execution run. If a build information file is not found on the execution server, the file is searched for on the application server. This behavior is beneficial when you have multiple execution servers and use a single build information file across all execution servers. You need to maintain only a single build information file on the application server. The build information files for automated tests that have no execution server assigned, and for all manual tests, are immediately searched for on the application server.
Silk Central is able to match up test results with build information and display test results for specific build numbers.
