To test:

Regression Notes

1. Potential unintended areas of impact

2. What I did to test those areas of impact (or what existing automated tests I relied on)

3. What automated tests I added (or what prevented me from doing so)

PR submission checklist:

• [ ] I have completed the Regression Notes.
• [ ] I have considered adding accessibility improvements for my changes.
• [ ] I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

@AjeshRPai - nice progress. I still need to take it out for a spin, only did a review of the code today

👋 @AjeshRPai - so this Debug View still doesn't match the existing behavior. Let me brain dump.

Excluding manual overrides, there are 3 possible values for every FF. (1) The build config value (2) The “FeatureConfig” class @Feature “default value” (3) The remote value (Firebase or our BE)

I think our issue lies within the confines of the pre-processing for the “default” value. This value appears to be set as the default if a remote field can’t be found in FB. Most of our FeatureConfig classes specify a remote field, but do NOT add a remote field into firebase, so I believe this “default value” is used in its place.

Take this example: Class = BloggingPromptsFeatureConfig Default value = true BuildConfig value = false Remote value = does not exist in Firebase

Comparing the value of blogging_prompts_remote_field within the debug setting view in the app: This PR: The field is unchecked Not this PR: The field is checked

The only difference between the two builds is the value of that default. Confused yet? 😉

Pull up funAppConfig.isEnabled and read the following comment - it clarifies the use of the build config.

/**
 * Get the enabled state of a feature flag. If the flag is enabled in the BuildConfig file, it overrides the remote
 * value. The correct approach is to disable a feature flag for a release version and only enable it remotely.
 * Once the feature is ready to be fully released, we can enable the BuildConfig value.
 * @param feature feature which we're checking remotely
 */

This matches the logic we see in AppConfig.buildFeatureState. In the above example the buildConfig = false, so when executing AppConfig.buildFeatureState we fall into the else statement remoteConfig.getFeatureState(feature.remoteField, feature.buildConfigValue) in which this PR returns the false value. My assumption is that we aren't using the "default" value like we did previously.

🤔 I wonder if we should be nulling out remote fields for FF that aren't using a remote companion field? Or they are there "just in case". Either way, if we want to match the current implementations we need to take that default value into account.

@AjeshRPai - Thanks for making the last round of changes. I was able to match the debug settings in this PR with the debug settings prior to this change. 👍

[enejb]

I updated the Label based on the testing we did yesterday. I think PR is ready to merge :shipit:

[AjeshRPai]

@enejb Thanks Enej 🙌🏼

@zwarm I have removed the redundant log messages from the PR. This PR is ready for another re-review.

I am working on fixing the CI failures. The failure seems to be because of a wire mock verification. Still looking into that.
