我正在将测试从我的rails / react应用程序中的Karma切换到Jest。通过遵循教程here，我解决了一些错误，并通过了一项PASS虚拟测试> cat sum_num.txt
26/06/2018 12890765 www.example.com 986.00
31/08/2018 17464946 www.other.com 7627.00
1/05/2018 65472345 www.example.com 14.00
> perl -ne ' { s/(.+)\s+(.+)$/\2/osmg;$x+=$_;print} END { print "Sum=$x\n"} ' sum_num.txt
986.00
7627.00
14.00
Sum=8627

exportApplicationGlobal: true这是终端输出：
spec/javascript/sum.test.js但是我的test('1 + 1 equals 2', () => {
expect(1 + 1).toBe(2);
})
以及我之前为Karma创建并后来适应Jest的其他测试都失败了。感觉我没有正确设置webpacker。
这是我的 PASS spec/javascript/sum.test.js
