I'm not sure this looks the way we want:

Side comment: in that screenshot I'm using the MUI TextField component in disabled mode. That seemed like the most straightforward way to add the namespace to the page. However, the colors on disabled text fields in MUI are low contrast, so I think I should probably re-implement the namespace as something else.

@smeragoel when you get a chance could you review this?

[peytondmurray]

This looks good - see comments though.

For my own understanding: why use mockTheme instead of <MockTheme> for that component here?

[gabalafou]

Good question. Two things:

1. I'm not super familiar with MUI or testing MUI. I was just patterning after what's already in this test file.
2. The function mockTheme is not written as a functional React component, but it could be.

The utility function is so lightweight that I'm thinking it might be better to replace the call to mockTheme() everywhere with:

import { condaStoreTheme } from "../src/theme";
// ...
<ThemeProvider theme={condaStoreTheme}>
  <Provider store={store}>
    <ComponentUnderTest />
  </Provider>
</ThemeProvider>

@gabalafou and I discussed this issue and we decided that we're gonna see how much effort it is to customize the input component to match the designs and then we can decide the way forward

[gabalafou]

Given the conversation in today's planning meeting, I reverted my last commit in favor of using the MUI TextField component without customization

Looks good - thanks for adding that aria-hidden property. Can you make sure the playwright tests are okay before merging?

[gabalafou]

The Playwright test is probably a legit failure. Need to investigate.

[gabalafou]

Merged since all checks pass!
