The regexp matches against the benchmark name, not the "full name". Slashes are interpreted as a separator for names to be matched against, thus your regexp first matches "^BenchmarkTextLayout" against all top-level benchmarks, then matches "CFFSimple1$" against all sub-benchmarks names found in "BenchmarkTextLayout" which indeed "CFFSimple1" and "OpenTypeCFFSimple1" are matches of. So the following regexp should only match "BenchmarkTextLayout/CFFSimple1". $ go test -bench='^BenchmarkTextLayout/^CFFSimple1$' Note the '^' before CFF.
