Variables ¶
var ErrMocked = trap.ErrMocked
ErrMocked indicates the target function is mocked and not called, instead result is set by the interceptor it is usually used to setup general mock interceptors example usage:
trap.AddInterceptor(&trap.Interceptor{
Pre: func(ctx context.Context, f *core.FuncInfo, args, result core.Object) (data interface{}, err error) {
if f.IdentityName == "Read" {
result.GetFieldIndex(0).SetInt(100)
return nil, trap.ErrMocked
}
return nil, nil
},
})
NOTE: this error should only be returned by interceptor in pre-phase. If it is returned in post-phase, it will cause xgo to panic.
Functions ¶
func AddFuncInterceptor ¶ added in v1.0.23
func AddFuncInterceptor(f interface{}, interceptor *Interceptor) func()
AddFuncInterceptor add func interceptor
func AddInterceptor ¶
func AddInterceptor(interceptor *Interceptor) func()
AddInterceptor add a general interceptor
func MarkIntercept ¶ added in v1.1.1
func MarkIntercept(f interface{})
MarkIntercept marks given function or variable to be intercepted, it serves as a compiler hint to xgo. it does not have any runtime behavior.
NOTE: you don't have to explicitly call this function if you called these functions in other places within the main module: - `mock.Patch(fn,...)`, `mock.Mock(fn,...)` - `trace.Record(fn,...)`, `trace.RecordCall(fn,...)` - `trap.AddFuncInterceptor(fn,...)` - `functab.InfoFunc(fn)`, `functab.InfoVar(addr)`
Example:
trap.MarkIntercept((*bytes.Buffer).String)
func MarkInterceptAll ¶ added in v1.1.2
func MarkInterceptAll()
MarkInterceptAll marks all functions to be intercepted this effectively enables the --trap-all flag unless explicitly disabled by --trap-all=false flag
