Go Webservice Example

This example is from CodiumAI’s cover-agent repository. The unit tests were generated using CodiumAI’s cover agent, and Mutahunter was used to verify the effectiveness of the test suite.

First generate test coverage report

go build
go install github.com/stretchr/testify/assert
go install github.com/axw/gocov/gocov
go install github.com/AlekSi/gocov-xml
go test -v -cover
go test -coverprofile=coverage.out
gocov convert coverage.out | gocov-xml > coverage.xml

Running Mutahunter to analyze the tests

Currently test coverage is 96.6%. Let's see what the mutation coverage is.

export OPENAI_API_KEY=your-key-goes-here

mutahunter run --test-command "go test" --code-coverage-report-path "coverage.xml" --only-mutate-file-paths "app.go" --model "gpt-4o-mini"

mutahunter gen --test-command "go test -coverprofile=coverage.out" --code-coverage-report-path "coverage.xml" --coverage-type cobertura --test-file-path "app_test.go" --source-file-path "app.go" --model "gpt-4o" --target-line-coverage 0.9 --max-attempts 3

gocov convert coverage.out | gocov-xml > coverage.xml # as there is no easy way to get direct coverage report from go test
