Reports 'No tests found in xxx' and silences error

Please provide details about:

What you're trying to do

I'm using v4. I used --experimental-loader, and this causes an error.

What happened

I just get No tests found.

What you expected to happen

When I look in the source:

The worker-failed message just reports it as "no declared tests", but ignores the actual error.

If you enable verbose it says ✖ src/index.test.ava.ts exited due to undefined.

It should print the full error if it doesn't recognize it without even without verbose. Silent errors are really bad.

    case 'worker-failed': {
                if (fileStats.declaredTests === 0) {
                    //console.log(event) <---------
                    this.filesWithoutDeclaredTests.add(event.testFile);
                }

                if (this.verbose && !this.filesWithMissingAvaImports.has(event.testFile)) {
                    if (event.nonZeroExitCode) {
                        this.lineWriter.writeLine(colors.error(`${figures.cross} ${this.relativeFile(event.testFile)} exited with a non-zero exit code: ${event.nonZeroExitCode}`));
                    } else {
                        this.lineWriter.writeLine(colors.error(`${figures.cross} ${this.relativeFile(event.testFile)} exited due to ${event.signal}`));
                    }
                }

                break;
            }

In my case it was a ERR_MODULE_NOT_FOUND message.

And even with verbose, for other errors, it trims the stack trace which is annoying.

Here are some more errors I got afterwards, but without a stack trace is impossible to debug.

  Uncaught exception in src/index.test.ava.ts

  TypeError: require(...).getRunner is not a function

  Uncaught exception in src/index.test.ava.ts

  TypeError: Cannot read property 'chalkOptions' of undefined

            case 'uncaught-exception': {
                this.uncaughtExceptions.push(event);

                if (this.verbose) {
                    this.lineWriter.ensureEmptyLine();
                    this.lineWriter.writeLine(colors.title(`Uncaught exception in ${this.relativeFile(event.testFile)}`));
                    this.lineWriter.writeLine();
                    this.writeErr(event);
                    console.log(event.stack) <-------- This is the stack which is hidden! Please print it when in verbose mode. Maybe add a `trace` mode!
                }

                break;
            }

And now I also get internal stack traces:
