You can run different defined groups of tests with
```bash
-gradle test -PtestngGroups=Network
+gradle test -Ptestng_groups=Network
```
Available groups include Functional (default), Network, External.
To exclude one or more groups of tests, add them as a comma separated list in testngExcludedGroups.
```bash
-gradle test -PtestngExcludedGroups=Not-bamboo
+gradle test -Ptestng_excluded_groups=Not-bamboo
```
+#### Viewing stdout and stderr for tests
+By default, gradle doesn't report any of the output or error streams produced by tests. You can enable output by setting the following:
+
+```bash
+gradle test -Ptest_output=1
+```
