VS Code 断点跳转到其他行

Question

As I haven't solved my other issue yet Randomly failing tests jest and supertest Node.js I've decided to use the VS Code debugger. I thought that it would be pretty simple but after I've set a breakpoint at the certain line and run the debugger I find my breakpoint icon in a different place and my code stops there.

My launch.json file:

{
    "type": "node",
    "request": "launch",
    "name": "Jest Current File",
    "program": "${workspaceFolder}/node_modules/jest/bin/jest",
    "args": ["${relativeFile}"]
}

Any idea why this happens?

Answer 1

I'm just using plain mocha, so might be a bit different. But I've noticed this before, and I would set an inline break point (cmd+shift+p - search inline breakpoint) inside the then()

Answer 2

Use .catch() after .then() , according to my experience, it isn't going to .then() due to some exception called and the catch is not invoked. I have worked on testing using chai mocha, had the same issue. Try to add .catch() it will show that your API might be faulty and reaching a catch statement.

您可以尝试清理您的工作区并创建一个新的launch.json文件

Answer 4

I had same problem, I've updated my VScode and change my Lunch file like this:

{
    "type": "node",
    "request": "launch",
    "name": "Jest tests",
    "program": "${workspaceRoot}/node_modules/jest/bin/jest.js",
    "args": ["--verbose", "-i", "--no-cache"],
    "console": "integratedTerminal",
    "internalConsoleOptions": "neverOpen"
}

Generally in some IDEs, the breakpoints are fixed to the line number. So if code in that file changes after the breakpoint is set, the breakpoint doesn't move. So when making changes,

• stop the debug mode
• make the changes
• set the breakpoint
• start debug mode again. This worked for me.

Answer 6

Execution is not going to that line due to some error thrown by the API request. Handle the error using catch block. Print the error in catch block. You can also add the break point for the code in catch block to check more details about the error.
