最佳答案
我从 Node 中的测试开始,使用 mocha、 chai 和 nock (拦截外部 HTTPapi 调用)。
我已经写了3个测试,他们都是一个通过,但是,当我添加第三个测试,摩卡停止退出后,运行的测试,没有错误或任何错误的迹象。
如果我注释第三个测试,摩卡就会退出。
这是导致“问题”的测试:
describe('tokenizer.processFile(req, \'tokenize\')', () => {
it('should tokenize a file', async () => {
req = {
file: {
originalname: 'randomcards.txt',
buffer: cardsFile_buffer
},
user: {
displayName: user
}
};
expect(Buffer.from(await tokenizer.processFile(req, 'tokenize'))).to.deep.equal(tokensFile_buffer);
});
});
再说一次,这个测试通过了,这让我很困惑。
下面是 tokenizer.processFile 的代码:
processFile: function(req, whatTo){
combinedLogger.info(`Request to ${whatTo} ${req.file.originalname} received. Made by: ${req.user.displayName}`);
return new Promise(function(resolve, reject){
const lines = [], responses = [];
const lineReader = require('readline').createInterface({
input: require('streamifier').createReadStream(req.file.buffer)
});
lineReader.on('line', line => {
lines.push(line);
});
lineReader.on('close', async () => {
//process every line sequentially
try {
//ensure DB connected to mass insert
await db_instance.get_pool();
for(const line of lines) {
var response;
req.current_value = line;
if (whatTo == 'tokenize'){
response = await Tokenize(line);
db_instance.insertAction(req, 'tokenize', response);
}
else if (whatTo == 'detokenize'){
combinedLogger.info(`Request to detokenize ${line} received. Made by: ${req.user.displayName}`);
response = await Detokenize(line);
db_instance.insertAction(req, 'detokenize', line);
}
responses.push(response);
}
resolve(responses.join("\r\n"));
}
catch(error){
reject(error);
}
});
});
}
函数 Tokenize (value)和 Detokenize (value)也在其他2个测试中被调用,当运行时,mocha 退出的很好。
知道是什么引起的吗?
