Go Code Coverage

Lets try to find the code coverage of Prometheus Volume exporter

Get Test coverage of package(s)

E:\practices\Go\volume_exporter>go test -cover github.com/mnadeem/volume_exporter/disk github.com/mnadeem/volume_exporter/exporter
ok      github.com/mnadeem/volume_exporter/disk 0.144s  coverage: 75.9% of statements
ok      github.com/mnadeem/volume_exporter/exporter     0.150s  coverage: 72.2% of statements

Generate coverage file

E:\practices\Go\volume_exporter>go test -cover github.com/mnadeem/volume_exporter/disk github.com/mnadeem/volume_exporter/exporter
ok      github.com/mnadeem/volume_exporter/disk 0.144s  coverage: 75.9% of statements
ok      github.com/mnadeem/volume_exporter/exporter     0.150s  coverage: 72.2% of statements
