Functions

func AssertMetricsUnique

func AssertMetricsUnique(ch chan *prometheus.Desc, t *testing.T)

AssertMetricsUnique takes metric descriptions from a channel and asserts they are unique

func CompareMetrics

func CompareMetrics(got map[string]float64, expected map[string]float64, t *testing.T)

CompareMetrics asserts all metrics that are expected are present and checks their value It does not complain about additional metrics being present

func PrepareErrorForTesting

func PrepareErrorForTesting(err error) connector.SSHCommandContext

PrepareErrorForTesting takes an error and returns a ssh command context that raises the error

func PrepareMetricsForTesting

func PrepareMetricsForTesting(ch chan prometheus.Metric, t *testing.T) map[string]float64

PrepareMetricsForTesting takes metrics from a channel and converts them to a map, mapping the metric (format `metric_example{label1=foo,bar=asdf}`) to it's value.

func PrepareOutputForTesting

func PrepareOutputForTesting(input string) connector.SSHCommandContext

PrepareOutputForTesting takes a string and returns a ssh command context that reads the input linewise

func Str2float64

func Str2float64(str string) float64

Str2float64 converts a string to float64
