Link to this function

get_best_effort_coverage(session, parameters \\ %{}, options \\ []) View Source 
get_best_effort_coverage(
  GenServer.server(),
  map(),
  Tungsten.Connection.exec_options()
) :: {:ok, %{result: [cdp_script_coverage_type()]}} | {:error, term()}

Profiler.getBestEffortCoverage

Collect coverage data for the current isolate. The coverage data may be incomplete due to garbage collection.

Link to this function

set_sampling_interval(session, parameters, options \\ []) View Source 
set_sampling_interval(
  GenServer.server(),
  %{interval: integer()},
  Tungsten.Connection.exec_options()
) :: {:ok, map()} | {:error, term()}

Profiler.setSamplingInterval

Changes CPU profiler sampling interval. Must be called before CPU profiles recording started.

Link to this function

start(session, parameters \\ %{}, options \\ []) View Source 
start(GenServer.server(), map(), Tungsten.Connection.exec_options()) ::
  {:ok, map()} | {:error, term()}

Profiler.start

This command has no documentation

Link to this function

start_precise_coverage(session, parameters \\ %{}, options \\ []) View Source 
start_precise_coverage(
  GenServer.server(),
  %{optional(:call_count) => boolean(), optional(:detailed) => boolean()},
  Tungsten.Connection.exec_options()
) :: {:ok, map()} | {:error, term()}

Profiler.startPreciseCoverage

Enable precise code coverage. Coverage data for JavaScript executed before enabling precise code coverage may be incomplete. Enabling prevents running optimized code and resets execution counters.

Link to this function

start_type_profile(session, parameters \\ %{}, options \\ []) View Source 
start_type_profile(
  GenServer.server(),
  map(),
  Tungsten.Connection.exec_options()
) :: {:ok, map()} | {:error, term()}

Profiler.startTypeProfile

Enable type profile.

Link to this function

stop(session, parameters \\ %{}, options \\ []) View Source 
stop(GenServer.server(), map(), Tungsten.Connection.exec_options()) ::
  {:ok, %{profile: cdp_profile_type()}} | {:error, term()}

Profiler.stop

This command has no documentation

Link to this function

stop_precise_coverage(session, parameters \\ %{}, options \\ []) View Source 
stop_precise_coverage(
  GenServer.server(),
  map(),
  Tungsten.Connection.exec_options()
) :: {:ok, map()} | {:error, term()}

Profiler.stopPreciseCoverage

Disable precise code coverage. Disabling releases unnecessary execution count records and allows executing optimized code.

Link to this function

stop_type_profile(session, parameters \\ %{}, options \\ []) View Source 
stop_type_profile(
  GenServer.server(),
  map(),
  Tungsten.Connection.exec_options()
) :: {:ok, map()} | {:error, term()}

Profiler.stopTypeProfile

Disable type profile. Disabling releases type profile data collected so far.

  map(),
  Tungsten.Connection.exec_options()
) :: {:ok, %{result: [cdp_script_coverage_type()]}} | {:error, term()}

Profiler.takePreciseCoverage

Collect coverage data for the current isolate, and resets execution counters. Precise code coverage needs to have started.

Link to this function

take_type_profile(
  GenServer.server(),
  map(),
  Tungsten.Connection.exec_options()
