Go mock function from extenal lib without interface
问题
我已经为我们的程序使用了以下日志记录器lib。
我们已经创建了单元测试，并且我们需要为版本0.4.0提供模拟。
https://github.com/go-logr/logr/blob/v0.4.0/logr.go#L148
这是我们如何模拟这些函数的方式，它们按预期工作。
type testLog struct {msg stringkey stringvalue string}func (log *testLog) Enabled() bool {return true}func (log *testLog) Info(msg string, keysAndValues ...interface{}) {log.msg = msglog.key = keysAndValues[0].(string)log.value = keysAndValues[1].(string)}func (log *testLog) Error(err error, msg string, keysAndValues ...interface{}) {}func (log *testLog) V(level int) logr.Logger {return &testLog{}}func (log *testLog) WithValues(keysAndValues ...interface{}) logr.Logger {return &testLog{}}func (log *testLog) WithName(name string) logr.Logger {return &testLog{}}
现在我们需要升级到版本1.2.0，实现已经改变，没有接口。
我的问题是，我应该如何使用新版本进行模拟记录器？
请参阅以下链接中的相关函数：
https://github.com/go-logr/logr/blob/v1.2.2/logr.go#L230
英文:
I’ve used the following logger lib for our program.
We have create unit tests and we need to provide mock for version 0.4.0
https://github.com/go-logr/logr/blob/v0.4.0/logr.go#L148
This is how we mocked the functions which works as expected
type testLog struct {msg stringkey stringvalue string}func (log *testLog) Enabled() bool {return true}func (log *testLog) Info(msg string, keysAndValues ...interface{}) {log.msg = msglog.key = keysAndValues[0].(string)log.value = keysAndValues[1].(string)}func (log *testLog) Error(err error, msg string, keysAndValues ...interface{}) {}func (log *testLog) V(level int) logr.Logger {return &testLog{}}func (log *testLog) WithValues(keysAndValues ...interface{}) logr.Logger {return &testLog{}}func (log *testLog) WithName(name string) logr.Logger {return &testLog{}}
Now we need to upgrade to version 1.2.0
And the implementation is changed, there is no interface.
My question is how should I mock the logger with the new version ?
See this link with the followed functions
https://github.com/go-logr/logr/blob/v1.2.2/logr.go#L230

我的问题是如何使用新版本来模拟日志记录器？
你不能这样做。需要采用一种非基于模拟的测试策略。

You cannot. Come up with a non mock-based testing strategy.
