[ML] Fractions API fix and jest unit tests for APM Latency Correlations. #103907

walterra · 2021-06-30T15:10:01Z

Summary

Follow up to #99905.

Adds jest unit tests for APM Latency Correlations code.

Writing the tests surfaced some minor glitches fixed as part of this PR:

Fixes a typo in the name for the fetchTransactionDurationPercentiles() function.
Avoids adding a @timestamp filter if neither start/end are set as parameters for getQueryWithParams().
Adds a check to only push to ranges arrays if it's length is already greater than 0.
Makes the check against from more strict otherwise it wouldn't be added as an attribute if 0.
Fixes progress calculation for field/value pair fetching.
Removes leading 0 from fractions since [ML] ensure the fractions and bucket doc count have the same lengths in bucket_count_ks_test elasticsearch#74624 got merged.
Removes deprecated use of track_total_hits.

Checklist

Unit or functional tests were updated or added to match the most common scenarios

+          },
+          size: 1000,
+          track_total_hits: true,


Looking at this again, I think we can remove this track_total_hits completely because we now use the totalDocCount from fetchTransactionDurationFractions for the histograms instead. This is something I should have removed in the last PR.

Good catch, removed it in f42dda2.

+
+  // fetchTransactionDurationPercentiles
+  if (req?.body?.aggs?.transaction_duration_percentiles !== undefined) {


nit: can we do an assertion for req?.body?.aggs? before these if statements so we don't have to duplicate these checks again?

Refactored in 16ef560.

Thanks for adding the unit tests. Changes LGTM 🎉 , just left a few minor comments.

Thanks for adding these. We usually don't add () in descriptions when describing functions so you can take those out if you like.

+  describe('getQueryWithParams()', () => {


Suggested change

describe('getQueryWithParams()', () => {

describe('getQueryWithParams', () => {

Thanks, updated in 02a1fd2.

+      });

+      it('performs a client search with params when no ID is provided', async () => {


I usually break these up if there's a when in there:

Suggested change

it('performs a client search with params when no ID is provided', async () => {

describe('when no ID is provided', () => {

it('performs a client search with params', async () => {

Updated in 44d5cc5.
