go-test

go-test

Generate test and benchmark functions of your Go functions.

Install

Install deep.

The following package will be used in your generated code : go get github.com/go-test/deep

Install go-test

go get github.com/cheikhshift/momentum/cmd/go-test

How it works

1. Add comment (on new line) @test to the function you wish to test.
2. Run $ go-test. (optional) Use flag workdir to specify path of directory with go sources.

CLI flags

  Usage of go-test:
  -bench
    	Run benchmark tests after source files are created.
  -test $ go test
    	Run $ go test after source files are created.
  -workdir string
    	Path of directory with go sources to convert.

Define test cases

Add a comment, to your function, with following format @case <input_variables> @equal <output_variables> to define a test case. Definitions of @case syntax :

1. <input_variables> : comma delimited function parameters (in Go syntax).. For example to test func Test(fnParam int) int, the comment would be // @case 40 @equal 50 (assuming Test adds 10 to fnParam).
2. <output_variables> : comma delimited function return values (in Go syntax). For example to test func Test(fnParam int) (int,error), the comment would be // @case 40 @equal 50,nil (assuming Test adds 10 to fnParam).

Interface functions

Following a comment with @case you may also define the interface to use with your test, as well as to compare with. The syntax to use is @obj <init_value> @equal <expected_value>.Definitions of @obj syntax :

1. <init_value> : Go syntax to create your functions interface. For example to test func (obj * SomeStruct) Test(fnParam int) int, the comment would be // @obj &SomeStruct{} @equal &SomeStruct{} .

   1. <expected_value> : comma delimited function return values (in Go syntax). For example to test func (obj * SomeStruct) Test(fnParam int) (int,error), the comment would be // @obj &SomeStruct{} @equal &SomeStruct{Var : "100"} (assuming Test updates the interface field Var to 100).

For example :

// @test
// @case "string" @equal "value string", nil
// @obj &Stk{Var : "Newva"} @equal &Stk{Var : "Newval"}
func (st * Stk) TestFunction (cas string) (res string,err error) {

Notes : You may need to update the imports of your generated file. In case you are comparing values from other packages. You may also use syntax @import <path_to_package>. For example // @import "path/to/pkg"
