## Learn Go with Testing

##### If you have been strict with TDD, it's quite likely you'll have close to 100% coverage anyway. go test -cover

###### Compile time errors are our friends because they help us write software that works

##### functions in Go are values.

##### Table Driven Tests are useful when you want to build a list of test cases. They are a great fit when you wish to test various implementations of an interface, or if the data being passed in to a function has lots of different requirements that need testing.

### Note:- By convention you should keep your method receiver types the same for consistency.

##### Errors can be converted to a string with the .Error() method.

##### An interesting property of maps is that you can modify them without passing as an address.A map value is a pointer to a runtime.hmap structure.

##### The Buffer type from the bytes package implements the Writer interface, buffer := bytes.Buffer{}

##### if a test is working with more than 3 mocks then it is a red flag - time for a rethink on the design.

##### ideally we don't want to be relying on external services to test our code because they can be Slow, Flaky, Can't test edge cases.

#####  the standard library, there is a package called net/http/httptest which enables users to easily create a mock HTTP server.

### in fact, in Go any is an alias for interface{}.

##### Reflection in computing is the ability of a program to examine its own structure, particularly through types.

##### (Context) Software often kicks off long-running, resource-intensive processes (often in goroutines). If the action that caused this gets cancelled or fails for some reason you need to stop these processes in a consistent way through your application.

### context package helps us to manage long-running processes.

### NOTE:- if a function needs some values, put them as typed parameters rather than trying to fetch them from context.Value.

### The problem with context.Values is that it's just an untyped map.
