Javascript 我们如何使用酶对功能组件内的功能进行单元测试？

对于类组件，我通常创建该组件的实例，并且可以访问该函数。我不知道如何访问功能组件的功能

const errorMessages = {
    browse: {
        fileLimit: 'File size is too big.',
        unsupportedFormat: 'The file you selected is not a supported format. Please upload a file in .csv format.',
        noRows: 'No agent IDS could be found.',
        maxAgents: 'A max of 25 agents can be uploaded at a time.',
        noValidAgents: 'No valid agents could be found.'
    },
    duplicate: 'The following agents are already existing on the table.'
};

例如，访问clearAllErrors或功能组件之外的errorMessages

const errorMessages = {
    browse: {
        fileLimit: 'File size is too big.',
        unsupportedFormat: 'The file you selected is not a supported format. Please upload a file in .csv format.',
        noRows: 'No agent IDS could be found.',
        maxAgents: 'A max of 25 agents can be uploaded at a time.',
        noValidAgents: 'No valid agents could be found.'
    },
    duplicate: 'The following agents are already existing on the table.'
};
