Cannot import chisel3.tester and chisel3.tester.RawTester.test

[JimmyCh1025]

Problem Description

When running the Chisel Bootcamp "2.1_first_module.ipynb" notebook in the official Docker container, I occurred issues with importing chisel3.tester and chisel3.tester.RawTester.test.

To Reproduce

1. Execute the first cell to load Ivy modules:

val path = System.getProperty("user.dir") + "/source/load-ivy.sc"
interp.load.module(ammonite.ops.Path(java.nio.file.FileSystems.getDefault().getPath(path)))

2. Execute the next cell:

import chisel3._
import chisel3.util._
import chisel3.tester._
import chisel3.tester.RawTester.test

Error

The following error occurred:

cmd2.sc:3: object tester is not a member of package chisel3
import chisel3.tester._
               ^cmd2.sc:4: object tester is not a member of package chisel3
import chisel3.tester.RawTester.test
               ^Compilation Failed

Compilation Failed

Attempts to Fix

To resolve the tester import issue, I attempted to downgrade chiseltest from 0.6.+ to 0.5.+. This resolved the import error, but it introduced a new issue related to json4s.
