Debug Point

Debug Point

Debug point is used in code test. When enabling a debug point, it can run related code.

Both FE and BE support debug points.

Code Example

FE example

private Status foo() {
// dbug_fe_foo_do_nothing is the debug point name.
// When it's active,DebugPointUtil.isEnable("dbug_fe_foo_do_nothing") will return true.
if (DebugPointUtil.isEnable("dbug_fe_foo_do_nothing")) {
return Status.Nothing;
}

do_foo_action();

return Status.Ok;
}

BE 桩子示例代码

void Status foo() {
// dbug_be_foo_do_nothing is the debug point name.
// When it's active,DEBUG_EXECUTE_IF will execute the code block.
DEBUG_EXECUTE_IF("dbug_be_foo_do_nothing", { return Status.Nothing; });

do_foo_action();

return Status.Ok;
}

Global config

To activate debug points, need set enable_debug_points to true.

enable_debug_points was located in FE's fe.conf and BE's be.conf。
