@naseemkullah process is only available within node, you need to have a different mecanism for the browser. We already have multiple functions that have different implementation depending on the platform here

packages/opentelemetry-core/src/utils/environment.ts

+  const regex = new RegExp(logLevelStrings.join('|'), 'i');
+  if (value && typeof value === 'string' && regex.test(value)) {


@naseemkullah would that work here?

Suggested change

const regex = new RegExp(logLevelStrings.join('|'), 'i');

if (value && typeof value === 'string' && regex.test(value)) {

if (logLevelStrings.includes(value)) {

Probably @iliasbhal but I just changed the function to a simpler switch case 😅

User can now control the log level by means of env var. Sets default log level to INFO as per open-telemetry#856 Also shares mock environment functions for tests to be used in ConsoleLogger tests as well as environment tests. Signed-off-by: Naseem <[email protected]>

Please excuse the force pushes, it is weekend and I presume nobody will be re-reviewing until Monday and would like a clean commit history by then.

+export function mockEnvironment(values: ENVIRONMENT_MAP) {


What's the reason you move it ?. keeping them just in tests it is fine, but exporting them as our sdk api with checking if process exists might not be a good solution Whatever we export to be a public must be platform dependent. If you are doing a helper function for you tests it is fine, but not when you try to export it.

@dyladan ^^

So the idea was to use it in multiple test files. While moving it here and exporting it so that multiple test files could use it seems to work it might not be the best solution.

We had a test-utils package but that was moved to contrib repo I believe. Should I copy paste these functions in both test files?

but it was inside file /test/utils/environment.test.ts which is perfectly fine, by moving this to environment.ts mean we are exporting a test function as our api which is not something we want

test-utils is in the contrib repo because it was only used by contrib plugins, but it might be a good idea to move it back into the main repo. I have said on other PRs I don't like the idea of exporting testing/fake/mock behavior from modules because users will find them and they will use them even if we dont want them to, and they will be confused and we will have to deal with it.

so you can still easily share this function between tests in the same package, just don't export them as our sdk

Thanks I will change accordingly as not to export the function

Alright, exported from its original location (test file itself) not sure why i did not do that first time around, think I was fatigued at that time.

just fix the conflicts pls
