我该如何进行分支测试，即使用笑话和酶进行SWITCH案例，IF和ELSE语句？

Question

我正在测试项目中的“卡片”组件。在类方法“ _handleInputValue”和“ _handleAuthorizeCardDetails”中，我有一系列嵌套的If和Else语句以及SWITCH案例。如何测试这些方法和其中嵌套的If Else语句？ 下面是类方法

_handleInputValue (e) {
        let inputField = e.target.name;
        console.log(inputField)
        if (inputField === 'pin'){
            console.log('pin')
            console.log(e.target.value.length)
            if (e.target.value.length > 4){
                return;
            }
            this.setState({
                [e.target.name] : e.target.value,
            });
        }
        
        if (inputField === 'otp'){
            console.log('otp')
            this.setState({
                [e.target.name] : e.target.value,
            });
            return;
        }
        
}
