|  | // This file and importx_test.go make it possible to write tests in the runtime | 
|  | // package, which is generally more convenient for testing runtime internals. | 
|  | // For tests that mostly touch public APIs, it's generally easier to write them | 
|  | // in the runtime_test package and export any runtime internals via | 
|  | // export_test.go. | 
|  | // | 
|  | // There are a few limitations on runtime package tests that this bridges: | 
|  | // | 
|  | // 1. Tests use the signature "XTest<name>(t TestingT)". Since runtime can't import | 
|  | // testing, test functions can't use testing.T, so instead we have the T | 
|  | // interface, which *testing.T satisfies. And we start names with "XTest" | 
|  | // because otherwise go test will complain about Test functions with the wrong | 
|  | // signature. To actually expose these as test functions, this file contains | 
|  | // trivial wrappers. | 
|  | // | 
|  | // 2. Runtime package tests can't directly import other std packages, so we | 
|  | // inject any necessary functions from std. | 
|  |  | 
|  | // TODO: Generate this |
