Interface Tracing

public interface Tracing

API for collecting and saving Playwright traces. Playwright traces can be opened in Trace Viewer after Playwright script runs.

Start recording a trace before performing actions. At the end, stop tracing and save it to a file.

 Browser browser = chromium.launch();
 BrowserContext context = browser.newContext();
 context.tracing().start(new Tracing.StartOptions()
   .setScreenshots(true)
   .setSnapshots(true));
 Page page = context.newPage();
 page.navigate("https://playwright.dev");
 context.tracing().stop(new Tracing.StopOptions()
   .setPath(Paths.get("trace.zip")));

Method Detail

start

default void start()

Start tracing.

 context.tracing().start(new Tracing.StartOptions()
   .setScreenshots(true)
   .setSnapshots(true));
 Page page = context.newPage();
 page.navigate("https://playwright.dev");
 context.tracing().stop(new Tracing.StopOptions()
   .setPath(Paths.get("trace.zip")));
 

start

void start(Tracing.StartOptions options)

Start tracing.

 context.tracing().start(new Tracing.StartOptions()
   .setScreenshots(true)
   .setSnapshots(true));
 Page page = context.newPage();
 page.navigate("https://playwright.dev");
 context.tracing().stop(new Tracing.StopOptions()
   .setPath(Paths.get("trace.zip")));
 

startChunk

default void startChunk()

Start a new trace chunk. If you'd like to record multiple traces on the same BrowserContext, use Tracing.start() once, and then create multiple trace chunks with Tracing.startChunk() and Tracing.stopChunk().

 context.tracing().start(new Tracing.StartOptions()
   .setScreenshots(true)
   .setSnapshots(true));
 Page page = context.newPage();
 page.navigate("https://playwright.dev");

 context.tracing().startChunk();
 page.click("text=Get Started");
 // Everything between startChunk and stopChunk will be recorded in the trace.
 context.tracing().stopChunk(new Tracing.StopChunkOptions()
   .setPath(Paths.get("trace1.zip")));

 context.tracing().startChunk();
 page.navigate("http://example.com");
 // Save a second trace file with different actions.
 context.tracing().stopChunk(new Tracing.StopChunkOptions()
   .setPath(Paths.get("trace2.zip")));
 

startChunk

void startChunk(Tracing.StartChunkOptions options)

Start a new trace chunk. If you'd like to record multiple traces on the same BrowserContext, use Tracing.start() once, and then create multiple trace chunks with Tracing.startChunk() and Tracing.stopChunk().

 context.tracing().start(new Tracing.StartOptions()
   .setScreenshots(true)
   .setSnapshots(true));
 Page page = context.newPage();
 page.navigate("https://playwright.dev");

 context.tracing().startChunk();
 page.click("text=Get Started");
 // Everything between startChunk and stopChunk will be recorded in the trace.
 context.tracing().stopChunk(new Tracing.StopChunkOptions()
   .setPath(Paths.get("trace1.zip")));

 context.tracing().startChunk();
 page.navigate("http://example.com");
 // Save a second trace file with different actions.
 context.tracing().stopChunk(new Tracing.StopChunkOptions()
   .setPath(Paths.get("trace2.zip")));
 

stop

default void stop()

Stop tracing.

stop

void stop(Tracing.StopOptions options)

Stop tracing.

stopChunk

default void stopChunk()

Stop the trace chunk. See Tracing.startChunk() for more details about multiple trace chunks.

stopChunk

void stopChunk(Tracing.StopChunkOptions options)

Stop the trace chunk. See Tracing.startChunk() for more details about multiple trace chunks.
