@openzeppelin/test-helpers

I am using @openzeppelin/test-helpers and create-react-app. Both install and use a version of webpack. However, to run the react app requires webpack v4.44.2 or higher but the version bundled into the test-helpers build is v3.12.0.

How can this problem be overcome? Can test-helpers be installed with a later version of webpack?

Test-helpers does not have a dependency on webpack. I'm not sure where you're seeing this?

Hi @frangio

If I install test-helpers into an empty directory webpack is installed. This older version of webpack is incompatible with create-react-app.

simonroope@MacBook testdir % npm list webpack
/Users/simonroope/testdir

Webpack should not be there. It's actually been removed in more recent versions but it hasn't been released yet.

@frangio Until the release of a newer version of test-helpers, that does not include webpack, what is a suggested solution to the problem? When might the newer version be available?
Many thanks
Simon

This is not a problem in OpenZeppelin Test Helpers. I also personally don't see how this can be causing issues for your project. But we don't have the bandwidth to help you debug it right now.
