  - CAPTURE_STDOUT_PROPERTY_NAME
```
public static final java.lang.String CAPTURE_STDOUT_PROPERTY_NAME
```
    Property name used to enable capturing output to System.out: "junit.platform.output.capture.stdout"
    By default, output to System.out is not captured.
    If enabled, the JUnit Platform captures the corresponding output and publishes it as a ReportEntry using the "stdout" key immediately before reporting the test identifier as finished.
    
    See Also:
    
    STDOUT_REPORT_ENTRY_KEY, ReportEntry, TestExecutionListener.reportingEntryPublished(TestIdentifier, ReportEntry), Constant Field Values
  - CAPTURE_STDERR_PROPERTY_NAME
```
public static final java.lang.String CAPTURE_STDERR_PROPERTY_NAME
```
    Property name used to enable capturing output to System.err: "junit.platform.output.capture.stderr"
    By default, output to System.err is not captured.
    If enabled, the JUnit Platform captures the corresponding output and publishes it as a ReportEntry using the "stderr" key immediately before reporting the test identifier as finished.
    
    See Also:
    
    STDERR_REPORT_ENTRY_KEY, ReportEntry, TestExecutionListener.reportingEntryPublished(TestIdentifier, ReportEntry), Constant Field Values
  - CAPTURE_MAX_BUFFER_PROPERTY_NAME
```
public static final java.lang.String CAPTURE_MAX_BUFFER_PROPERTY_NAME
```
    Property name used to configure the maximum number of bytes for buffering to use per thread and output type if output capturing is enabled: "junit.platform.output.capture.maxBuffer"
    Value must be an integer; defaults to 4194304.
    
    See Also:
    
    CAPTURE_MAX_BUFFER_DEFAULT, Constant Field Values
  - CAPTURE_MAX_BUFFER_DEFAULT
```
public static final int CAPTURE_MAX_BUFFER_DEFAULT
```
    Default maximum number of bytes for buffering to use per thread and output type if output capturing is enabled.
    
    See Also:
    
    CAPTURE_MAX_BUFFER_PROPERTY_NAME, Constant Field Values
  - STDOUT_REPORT_ENTRY_KEY
```
public static final java.lang.String STDOUT_REPORT_ENTRY_KEY
```
    Key used to publish captured output to System.out as part of a ReportEntry: "stdout"
    
    See Also:
    
    Constant Field Values
  - STDERR_REPORT_ENTRY_KEY
```
public static final java.lang.String STDERR_REPORT_ENTRY_KEY
```
    Key used to publish captured output to System.err as part of a ReportEntry: "stderr"

    Constant Field Values
  - DEACTIVATE_LISTENERS_PATTERN_PROPERTY_NAME
```
public static final java.lang.String DEACTIVATE_LISTENERS_PATTERN_PROPERTY_NAME
```
    Property name used to provide patterns for deactivating listeners registered via the ServiceLoader mechanism: "junit.platform.execution.listeners.deactivate"
    Pattern Matching Syntax
    
    If the property value consists solely of an asterisk (*), all listeners will be deactivated. Otherwise, the property value will be treated as a comma-separated list of patterns where each individual pattern will be matched against the fully qualified class name (FQCN) of each registered listener. Any dot (.) in a pattern will match against a dot (.) or a dollar sign ($) in a FQCN. Any asterisk (*) will match against one or more characters in a FQCN. All other characters in a pattern will be matched one-to-one against a FQCN.
    Examples
    
    *: deactivates all listeners.
    org.junit.*: deactivates every listener under the org.junit base package and any of its subpackages.
    *.MyListener: deactivates every listener whose simple class name is exactly MyListener.
    *System*, *Dev*: deactivates every listener whose FQCN contains System or Dev.
    org.example.MyListener, org.example.TheirListener: deactivates listeners whose FQCN is exactly org.example.MyListener or org.example.TheirListener.

    DEACTIVATE_ALL_LISTENERS_PATTERN, TestExecutionListener, Constant Field Values
  - DEACTIVATE_ALL_LISTENERS_PATTERN
```
public static final java.lang.String DEACTIVATE_ALL_LISTENERS_PATTERN
```
    Wildcard pattern which signals that all listeners registered via the ServiceLoader mechanism should be deactivated: "*"

    DEACTIVATE_LISTENERS_PATTERN_PROPERTY_NAME, TestExecutionListener, Constant Field Values
  - ENABLE_LAUNCHER_INTERCEPTORS
```
@API(status=EXPERIMENTAL,
     since="1.10")
public static final java.lang.String ENABLE_LAUNCHER_INTERCEPTORS
```
    Property name used to enable support for LauncherInterceptor instances to be registered via the ServiceLoader mechanism: "junit.platform.launcher.interceptors.enabled"
    By default, interceptor registration is disabled.
    
    See Also:
    
    LauncherInterceptor, Constant Field Values
  - DRY_RUN_PROPERTY_NAME
```
@API(status=EXPERIMENTAL,
     since="1.10")
public static final java.lang.String DRY_RUN_PROPERTY_NAME
```
    Property name used to enable dry-run mode for test execution.
    When dry-run mode is enabled, no tests will be executed. Instead, all registered TestExecutionListeners will receive events for all test descriptors that are part of the discovered TestPlan. All containers will be reported as successful and all tests as skipped. This can be useful to test changes in the configuration of a build or to verify a listener is called as expected without having to wait for all tests to be executed.
    Value must be either true or false; defaults to false.
    
    See Also:
    
    Constant Field Values
  - STACKTRACE_PRUNING_ENABLED_PROPERTY_NAME
```
@API(status=EXPERIMENTAL,
     since="1.10")
public static final java.lang.String STACKTRACE_PRUNING_ENABLED_PROPERTY_NAME
```
    Property name used to enable or disable stack trace pruning.
    By default, stack trace pruning is enabled.
