Support for mocks in tests #137
Description
Majority of the functions involve calls to functions from external packages which need to be mocked. Adding support for mocks can take gotests to the next level I believe.
e.g. An example function and its generated test can look something like this (pseudocode)
CODE
package A
import B
func fA(in) out{
...
resp := B.fB(p1, p2)
...
}TEST
package A
import bmock
func TestfA(t *testing.T) {
type mockB struct {
resp // mock resp of B.fB
times // number of times B.fB will be called
}
testCases := []struct {
name
args
mockB
want
} { // add testcases }
for _, tc := range testCases {
t.Run(tc.name, func(t *testing.T) {
gmc := gomock.NewController(t)
defer gmc.Finish()
bStub := bmock.NewMockService(t) // just an example, this is debatable
bstub.Expect().fB(gomock.Any(), gomock.Any()). // 2 params so 2 gomock.Any()
Times(tc.mockB.times).
Return(tc.mockB.resp)
...... // existing logic follows
})
}
}I would first like to ask whether you have already thought about the feasibility of this idea. If you feel this is possible, I would love to work on this enhancement.
