# Playwright Trace CLI
|
| 8 |
-
|
| 9 |
-
Inspect `.zip` trace files produced by Playwright tests without opening a browser.
|
| 10 |
-
|
| 11 |
-
## Workflow
|
| 12 |
-
|
| 13 |
-
1. Start with `trace open <trace.zip>` to extract the trace and see its metadata.
|
| 14 |
-
2. Use `trace actions` to see all actions with their action IDs.
|
| 15 |
-
3. Use `trace action <action-id>` to drill into a specific action — see parameters, logs, source location, and available snapshots.
|
| 16 |
-
4. Use `trace requests`, `trace console`, or `trace errors` for cross-cutting views.
|
| 17 |
-
5. Use `trace snapshot <action-id>` to get the DOM snapshot, or run a browser command against it.
|
| 18 |
-
6. Use `trace close` to remove the extracted trace data when done.
|
| 19 |
-
|
| 20 |
-
All commands after `open` operate on the currently opened trace — no need to pass the trace file again. Opening a new trace replaces the previous one.
|
| 21 |
-
|
| 22 |
-
## Commands
|
| 23 |
-
|
| 24 |
-
### Open a trace
|
| 25 |
-
|
| 26 |
-
```bash
|
| 27 |
-
# Extract trace and show metadata: browser, viewport, duration, action/error counts
|
| 28 |
-
npx playwright trace open <trace.zip>
|
| 29 |
-
```
|
| 30 |
-
|
| 31 |
-
### Close a trace
|
| 32 |
-
|
| 33 |
-
```bash
|
| 34 |
-
# Remove extracted trace data
|
| 35 |
-
npx playwright trace close
|
| 36 |
-
```
|
| 37 |
-
|
| 38 |
-
### Actions
|
| 39 |
-
|
| 40 |
-
```bash
|
| 41 |
-
# List all actions as a tree with action IDs and timing
|
| 42 |
-
npx playwright trace actions
|
| 43 |
-
|
| 44 |
-
# Filter by action title (regex, case-insensitive)
|
| 45 |
-
npx playwright trace actions --grep "click"
|
| 46 |
-
|
| 47 |
-
# Only failed actions
|
| 48 |
-
npx playwright trace actions --errors-only
|
| 49 |
-
```
|
| 50 |
-
|
| 51 |
-
### Action details
|
| 52 |
-
|
| 53 |
-
```bash
|
| 54 |
-
# Show full details for one action: params, result, logs, source, snapshots
|
| 55 |
-
npx playwright trace action <action-id>
|
| 56 |
-
```
|
| 57 |
-
|
| 58 |
-
The `action` command displays available snapshot phases (before, action, after) and the exact command to extract them.
|
| 59 |
-
|
| 60 |
-
### Requests
|
| 61 |
-
|
| 62 |
-
```bash
|
| 63 |
-
# All network requests: start time (on the `trace actions` clock), method, status, URL, duration, size
|
| 64 |
-
npx playwright trace requests
|
| 65 |
-
|
| 66 |
-
# Filter by URL pattern
|
| 67 |
-
npx playwright trace requests --grep "api"
|
| 68 |
-
|
| 69 |
-
# Filter by HTTP method
|
| 70 |
-
npx playwright trace requests --method POST
|
| 71 |
-
|
| 72 |
-
# Only failed requests (status >= 400)
|
| 73 |
-
npx playwright trace requests --failed
|
| 74 |
-
```
|
| 75 |
-
|
| 76 |
-
### Request details
|
| 77 |
-
|
| 78 |
-
```bash
|
| 79 |
-
# Show full details for one request: headers, body, security
|
| 80 |
-
npx playwright trace request <request-id>
|
| 81 |
-
```
|
| 82 |
-
|
| 83 |
-
### Console
|
| 84 |
-
|
| 85 |
-
```bash
|
| 86 |
-
# All console messages and stdout/stderr
|
| 87 |
-
npx playwright trace console
|
| 88 |
-
|
| 89 |
-
# Only errors
|
| 90 |
-
npx playwright trace console --errors-only
|
| 91 |
-
|
| 92 |
-
# Only browser console (no stdout/stderr)
|
| 93 |
-
npx playwright trace console --browser
|
| 94 |
-
|
| 95 |
-
# Only stdout/stderr (no browser console)
|
| 96 |
-
npx playwright trace console --stdio
|
| 97 |
-
|
| 98 |
-
# Filter by message text pattern
|
| 99 |
-
npx playwright trace console --grep "failed to fetch"
|
| 100 |
-
```
|
| 101 |
-
|
| 102 |
-
### Errors
|
| 103 |
-
|
| 104 |
-
```bash
|
| 105 |
-
# All errors with stack traces and associated actions
|
| 106 |
-
npx playwright trace errors
|
| 107 |
-
```
|
| 108 |
-
|
| 109 |
-
### Snapshots
|
| 110 |
-
|
| 111 |
-
The `snapshot` command loads the DOM snapshot for an action into a headless browser and runs a single browser command against it. Without a browser command, it returns the accessibility snapshot.
|
| 112 |
-
|
| 113 |
-
```bash
|
| 114 |
-
# Get the accessibility snapshot (default)
|
| 115 |
-
npx playwright trace snapshot <action-id>
|
| 116 |
-
|
| 117 |
-
# Use a specific phase
|
| 118 |
-
npx playwright trace snapshot <action-id> --phase before
|
| 119 |
-
|
| 120 |
-
# Run eval to query the DOM
|
| 121 |
-
npx playwright trace snapshot <action-id> -- eval "document.title"
|
| 122 |
-
npx playwright trace snapshot <action-id> -- eval "document.querySelector('#error').textContent"
|
| 123 |
-
|
| 124 |
-
# Eval on a specific element ref (from the snapshot)
|
| 125 |
-
npx playwright trace snapshot <action-id> -- eval "el => el.getAttribute('data-testid')" e5
|
| 126 |
-
|
| 127 |
-
# Take a screenshot of the snapshot
|
| 128 |
-
npx playwright trace snapshot <action-id> -- screenshot
|
| 129 |
-
|
| 130 |
-
# Redirect output to a file
|
| 131 |
-
npx playwright trace snapshot <action-id> -- eval "document.body.outerHTML" --filename=page.html
|
| 132 |
-
npx playwright trace snapshot <action-id> -- screenshot --filename=screenshot.png
|
| 133 |
-
```
|
| 134 |
-
|
| 135 |
-
Only three browser commands are useful on a frozen snapshot: `snapshot`, `eval`, and `screenshot`.
|
| 136 |
-
|
| 137 |
-
### Attachments
|
| 138 |
-
|
| 139 |
-
```bash
|
| 140 |
-
# List all trace attachments
|
| 141 |
-
npx playwright trace attachments
|
| 142 |
-
|
| 143 |
-
# Extract an attachment by its number
|
| 144 |
-
npx playwright trace attachment 1
|
| 145 |
-
npx playwright trace attachment 1 -o out.png
|
| 146 |
-
```
|
| 147 |
-
|
| 148 |
-
## Typical investigation
|
| 149 |
-
|
| 150 |
-
```bash
|
| 151 |
-
# 1. Open the trace and see what's inside
|
| 152 |
-
npx playwright trace open test-results/my-test/trace.zip
|
| 153 |
-
|
| 154 |
-
# 2. What actions ran?
|
| 155 |
-
npx playwright trace actions
|
| 156 |
-
|
| 157 |
-
# 3. Which action failed?
|
| 158 |
-
npx playwright trace actions --errors-only
|
| 159 |
-
|
| 160 |
-
# 4. What went wrong?
|
| 161 |
-
npx playwright trace action 12
|
| 162 |
-
|
| 163 |
-
# 5. What did the page look like at that moment?
|
| 164 |
-
npx playwright trace snapshot 12
|
| 165 |
-
|
| 166 |
-
# 6. Query the DOM for more detail
|
| 167 |
-
npx playwright trace snapshot 12 -- eval "document.querySelector('.error-message').textContent"
|
| 168 |
-
|
| 169 |
-
# 7. Any relevant network failures?
|
| 170 |
-
npx playwright trace requests --failed
|
| 171 |
-
|
| 172 |
-
# 8. Any console errors?
|
| 173 |
-
npx playwright trace console --errors-only
|
| 174 |
-
