Analysis of Robot reports from OSM Jenkins

Date and time of the report: 2026-01-18 08:45:15.191039

Analysed period: 2025-12-28 to 2026-01-18.

1. Retrieval of all currrent data for aggregate analytics

Database update:

Retrieving new jobs...

Getting new builds from: osm-stage_3-merge/master, osm-stage_3-merge/v18.0, osm-stage_3-merge/v17.0, osm-stage_3-merge/v16.0, osm-stage_3-merge/v14.0

2. Aggregated analysis of stability

2.1 Restricts data to time window for analysis

2.2 Finding sequences of successful builds and Robot reports

Two values retrieved from the build are key to determine the state of the jubs and test suites at a given moment:

• build_result is the outcome of the build, reported by Jenkins. It can be: SUCCESS, FAILURE, UNSTABLE or ABORTED.
• test_result is the summary of the concerned Robot tests. It can be: FAIL, UNAVAILABLE or PASS.

Based on these two states, 3 types of temporal sequences of success/failure are identified per builds and test suites:

1. Successful builds/failed builds in a row: grp_build_result.
2. Successful test reports vs. test reports with fails in a row: grp_test_result.
3. Clean builds and tests vs. failures (of any kind) in a row: grp_success_fail.

For the identification of these sequences, the following mapping applies:

Type of sequence	Relevant state	OK sequence contains	NOK sequence contains	Ignore
grp_build_result	build_result	SUCCESS or UNSTABLE	FAILURE	ABORTED
grp_test_result	test_result	PASS	FAIL	UNAVAILABLE
grp_success_fail	test_result	PASS	FAIL or UNAVAILABLE	N/A

The different groupings of segments are detected and a label is added to each sample...

DONE

Then, the duration of each of the sequences of success/failure is determined and a specific dataframe is built summarizing such sequences, to ease their representation and analysis...
