Test results matter less than what you do with them. A passing test nobody looks at is dead code. A failing test without context is noise. Good test reporting surfaces actionable signal. This guide covers how to build reports that developers actually read.

What good reports show

1. Pass / fail status — obvious
2. Time to diagnose — logs, screenshots, stack traces in one place
3. Flakiness context — is this new, or has it been flaking for weeks?
4. Ownership — who fixes this?
5. Priority signal — critical path or long-tail?

Report layers

Per-test

• Pass / fail
• Duration
• Output / stack trace on failure
• Screenshots before / after failure point
• Video of test run (on failure)
• Network log (HAR) if relevant

Per-run

• Summary: X/Y passed
• Duration
• New failures vs pre-existing
• Flaky tests called out
• Coverage delta

Cross-run

• Historical pass rate per test
• Trend: getting better or worse
• Flakiness score per test
• Coverage over time

Tools

Standard formats

• JUnit XML: universal, CI-consumable
• Allure: rich, JS-based dashboards
• Playwright HTML report: built-in, good
• Cypress Dashboard: hosted, good if using Cypress

Custom

• Dump to CI status check
• Slack notification on regression
• Email digest weekly

Observability

• Sentry / DataDog for flaky test tracking
• Custom dashboards of key metrics

Integration patterns

CI status check

PR shows pass/fail per check. Link to full report. Blocking vs advisory.

Slack

@team Test run on PR #123: 2 new failures in auth suite
  [View report](link)

Dashboard

Permanent dashboard visible to team. Trends visible. Owner assignments.

Alerting

New failure in critical path → page. New failure in long-tail → log.

Anti-patterns

Report with no context

"Test failed" without logs → nobody fixes.

Firehose

Every run posts to Slack → banner blindness.

No trend data

New flake looks like same old flake → no one notices worsening.

Green dashboard lies

Quarantined failures don't show red → "all green" means "we ignored the reds."

No owner

Failing test with no one responsible → sits forever.

Best practices

1. Failure has actionable details

Stack, screenshot, video, log excerpt, repro command. One click to debug.

2. Separate new from existing

"You broke this" vs "this has been broken" are different problems.

3. Flakiness tracked

Metric per test. Retried-but-passed-eventually is flake, not pass.

4. Ownership automatic

CODEOWNERS file maps test paths to teams. Report tags.

5. Historical context

"This test last failed 3 months ago" vs "this test fails daily" — different meanings.

6. Coverage as context

If critical path has <70% coverage, flag it. Coverage lines changed in PR.

How SUSA reports

SUSA produces per-session reports:

• HTML report with full exploration timeline
• JSON for programmatic consumption
• JUnit XML for CI integration
• Per-finding: screenshot, action, step, severity
• Coverage metrics: screens seen, elements tapped, flows completed
• Regression diff vs previous session

susatest-agent test myapp.apk --format html,junit-xml --output results/

Cross-session analytics

Track over time:

• Coverage growth
• Finding count by severity
• Crash rate
• Performance trend (cold start, jank)
• Regression diffs

Report readability rules

• First screen shows summary. Drill-down for details.
• Failures highlighted, passes de-emphasized. Signal-to-noise matters.
• Link to source code line. "Failed at Login.test.ts:42" clickable.
• Time-stamped. When did this run?
• Version tagged. Which build?
• Environment tagged. Which staging / prod?

Reports for stakeholders

Executives

Release confidence: pass rate, critical-path coverage, known issues.

Engineering

Per-test detail, flake rate, ownership.

QA

Exploratory session findings, regression triage queue.

Product

Flow verdicts, coverage of new features, user-impact issues.

Tailor views. Same underlying data, different aggregations.

Test reporting is an ongoing investment. Good reports compound — every debug cycle is faster. Invest in quality tooling; the ROI is team velocity.
