我不能用Jest运行多个测试文件？
我今天刚刚开始与Jest。 我在__tests__目录中有一个简单的测试文件。 这是当前的测试文件：
describe('ChangeCalendarView', function() {
it('true', function() {
expect(3).toBe(3);
})
});
这运行没有问题。 当我添加另一个文件时，使用相同的确切代码，而不是描述：
describe('ChangeTimePeriod', function() {
it('true', function() {
expect(3).toBe(3);
})
});
然后我得到这个错误：
/usr/local/lib/node_modules/jest-cli/node_modules/node-worker-pool/Worker.js:93
throw new Error('Received unexpected data from child process: ' + data);
^
Error: Received unexpected data from child process: {
"error": "Error: ENOENT, open '/usr/local/lib/node_modules/jest-cli/.haste_cache/cache-react-calendar-component'nn"
}
at Worker._onStdout (/usr/local/lib/node_modules/jest-cli/node_modules/node-worker-pool/Worker.js:93:11)
这对任何人都有意义吗？
我已经通过使用babel-jest解决了这个问题。 在这里我的package.json

Jest使用的glob模式来检测测试文件。 默认情况下，它会在测试文件夹内查找.js和.jsx文件，以及任何带有.test或.spec后缀的文件（例如Component.test.js或Component.spec.js）。 它还会找到名为test.js或spec.js的文件。 所以用你的测试文件命名为.test .Like pagination.test.js。
