Description

Utility functions to capture standard output, error output, or log output

Testing

Unit tests can be started by the following command:

./test.sh

It is also possible to specify CLI options for Go test. For example, if you need to disable test results caching, use the following command:

./test -count=1

CI

Travis CI is configured for this repository. Several tests and checks are started for all pull requests:

• Unit tests that use the standard tool go test
• go fmt tool to check code formatting. That tool is run with -s flag to perform following transformations
• go vet to report likely mistakes in source code, for example suspicious constructs, such as Printf calls whose arguments do not align with the format string.
• golint as a linter for all Go sources stored in this repository
• gocyclo to report all functions and methods with too high cyclomatic complexity. The cyclomatic complexity of a function is calculated according to the following rules: 1 is the base complexity of a function +1 for each 'if', 'for', 'case', '&&' or '||' Go Report Card warns on functions with cyclomatic complexity > 9

History of checks done by CI is available at RedHatInsights / insights-operator-controller.

Functions

func ErrorOutput

func ErrorOutput(function func()) (string, error)

ErrorOutput captures the error output for specified code block and then returns the captured output. Please see https://medium.com/@hau12a1/golang-capturing-log-println-and-fmt-println-output-770209c791b4 for further explanation how it works under the hood.

func StandardOutput

func StandardOutput(function func()) (string, error)

StandardOutput captures the standard output for specified code block and then returns the captured output. Please see https://medium.com/@hau12a1/golang-capturing-log-println-and-fmt-println-output-770209c791b4 for further explanation how it works under the hood.
