Feature and motivation

Overview

EdgeDriverService in Selenium Java binding has six properties; webdriver.edge.driver, webdriver.edge.logfile, webdriver.edge.verboseLogging, webdriver.edge.silentOutput, webdriver.edge.withAllowedIps, and webdriver.edge.disableBuildCheck. These options are very helpful in operating Edge server nodes.

One feature I feel missing is that there are no APIs to customize the log level.

Current possible solutions

For example, when I want to set the log-level=INFO, I have only one option, to set the --log-level option to msedgedriver directly.

$ ./msedgedriver --log-level=INFO

However, this way has some drawbacks.

First, it requires us a complex flow which combines with the system property webdriver.edge.driver and some wrapped scripts.

For example: set a wrapper batch file to the webdriver.edge.driver property.

java -Dwebdriver.edge.driver=edgedriver_wrapper.bat

And then, a wrapped batch file execute msedgedriver with the --log-level option.

C:\path\msedgedriver.exe --log-level $args

Another drawback is that command option settings must be written in multiple places. I understand that it doesn't make sense to support ALL options (e.g. an experimental option --replayable). But I believe the --log-level is commonly helpful, as is the --verbose option.

In addition, the property webdriver.edge.verboseLogging is not a perfect solution because it indicates to set the option --verbose option (equivalent to --log-level=ALL).

Usage example

We can use the new system property like this:

System.setProperty("webdriver.edge.loglevel", "INFO");
EdgeDriverService service = EdgeDriverService.createDefaultService();

EdgeDriver driver = new EdgeDriver(service);
