1. Support Subtests and Sub-benchmarks
Table-driven testing is a best practice for Golang built-in testing framework, based on the idea of table-driven testing, Go 1.7 Further improved the testing organizational system, adding subtests and Sub-benchmarks. The goal is to achieve the following features:
The external command line (go test–run=xx) allows you to select a test or benchmark from a table for debugging purposes;
Simplify the
Q 1:
Class test{Private $AA = 1;function __get ($proName) {return $this->proname;}}Class Subtest extends test{Private $AA = 2;}$test =new subtest ();Echo $test->aa;
For explanation, why output 1?
A: When attempting to access a private property from outside the class, the __get method is called, if it exists, subtest inherits the test class and tries to overloa

The use of if and ElseIf in VB is:If...then...elseif...then...else...endifRemember to do not add a colon after then, add a colon to the else without an if error, because the addition of a colon means that if the statement is only executed then, even if the execution is finished, so the following1 SubTest ()2 DimI as Integer3 DimJ as Integer4 Dima5 fori =1 to 2:6Debug.Print ("This is the first"Str(i) "Secondary Cycle")7A =InputBox("Please enter")8

1. Overloading:Overloading is a series of functions in which a class, like a function name, has a different parameter type or number of argumentsIt is important to note that it is independent of the return type. class test{ public : void show (); void Show (int a); void Show (double a); void Show (int a,int b); void Show (int a,double b);}; 2. RewriteAnother word we're more familiar with is "overlay."In the case of inheritance, if the subclass does not redefine the vi

influence of the number threads was similar to the results shown here (with the exception of random read multiple files; see below ). to suppress caching effects with the test, I used differentSet of files for each subtest with 1, 2..., 32 threads.
Theoretical Aspects
Before discussing the results, it is important to consider a few important I/O issues.
Read caching. All modern operating systems use all available memory to cache the most recently u

What the? Is it an out parameter, but we have to use it for the parameter of the method to be valid? At first glance there will be some surprises. We need to take some trouble to understand the problem. Now we consider ibarreversed into ifooif an interface requires a T covariance, then the parameter type

enables uses like Table-driven benchmarks and creating hierarchical tests. It also provides a to share common setup and Tear-down code:
Func Testfoo (t *testing. T) { //
Each subtest and Sub-benchmark have a unique name:the combination of the name of the top-level test and the sequence of NA Mes passed to Run, separated by slashes, with a optional trailing sequence number for disambiguation.

, all logger are organized through a hierarchical structure, with a root-level logger, which can be obtained in the following ways:Logger root = Logger::getroot ();User-defined logger have a name corresponding to them, such as:Logger test = logger::getinstance ("test");You can define the child logger of the logger:Logger subtest = logger::getinstance ("Test.subtest");Note that the root level of Logger is only obtained through the Getroot method, and L
