This function normalizes the `context` field in testthat test results. Some test result objects may have missing, empty, or `NA` context values. This helper function assigns a meaningful context by using the associated file name (excluding the `.R` extension) whenever the original context is unavailable.
fix_test_context(test_results)A list of test result objects where all entries have a non-empty `context` value. If a test result originally lacked a valid context, its context is replaced by the corresponding test file name. The structure of each test result object is otherwise unchanged.
This output is used by downstream functions that rely on context labels for grouping, mapping, or summarizing test outcomes.
A list of test result objects produced by testthat execution functions (e.g., `testthat::test_dir()` or internal STF reporter helpers). Each element should contain a `context` field.
