1. A computer implemented method to in-line script dependencies, comprising: extracting test resources addressed in language defining a test web page; placing markers identifying a location of each extracted test resource within the language defining the test page; iteratively loading, into non-transitory memory, external resources associated with a path of each test resource; analyzing each test resource to identify one or more dynamically added dependencies based on any corresponding resource requirement calls in the test resource referencing the one or more dynamically added dependencies, each dynamically added dependency comprising a script or file; adding each identified dependency after or before a top level parent resource; performing the analyzing and the adding until no new dependencies are identified; providing each new dependency with a reference to a parent marker associated with the top level parent resource; and replacing each marker with external resources and dependencies that reference their respective marker to generate updated language defining an updated test page; wherein each step is performed using one or more processors.
