如何在test中调用已安装的Provider中的React组件的方法

Question

我用酶编写单元测试并尝试调用组件的方法。

let wrapper = mount(<Provider>
                        <MyComponent />
                      </Provider>);

如何调用MyComponent的方法？

我会为此做一个浅包装。

#include <iostream>

using namespace std;

int main(){
    char choice;
    int num1, num2;
    int getNums();
    int operatorChoice()
    int multiply(int, int);
    int subtract(int, int);
    int add(int, int);
    void outputResult(int);
    getNums();
    int result;
    operatorChoice();
    if(choice == 'A'){
        add(num1,num2);
    }
    if(choice == 'S'){
        subtract(num1, num2);
    }else{
        multiply(num1,num2);
        outputResult(result);
        return 0;
    }
}
int getNums(){
    int num1,num2;
    cout << "Enter an integer " << endl;
    cin >> num1;
    cout << "Enter an integer " << endl;
    cin >> num2;
    return num1, num2;
}
int operatorChoice(){
    char choice;
    cout << "Enter A to add, S to subtract, or M to multiply " << endl;
    cin >> choice;
    while(choice != 'A' && choice !='S' && choice != 'M'){
        cout << "Invalid choice. Enter A to add, S to subtract, or M to 
multiply ";
        cin >> choice;
    }
    return choice;
}
int add(){
    int num1, num2;
    int result;
    result = num1 + num2;
    return result;
}
int subtract(){
    int num1, num2;
    int result;
    result = num1 - num2;
    return result;
}
int multiply(){
    int num1, num2;
    int result;
    result = num1 * num2;
    return result;
}
void outputResult(){
    int result;
    cout << "The result is " << result << endl;
}
