Configuration

There are multiple properties files located in src/main/resources:

  • _api.properties - API test endpoints reference
  • _config.properties - global test configuration
  • _database.properties - database connection properties
  • _email.properties - emailable reports config
  • _testdata.properties - test user credentials

All the properties may be retrieved in a test using R class:

R.API.get("GetUserMethods")
R.CONFIG.get("browser")
R.DATABASE.get("db.url")
R.EMAIL.get("title")
R.TESTDATA.get("user.email")

The default config properties can be obtained by

Configuration.get(Parameter.BROWSER)

All the project configuration properties are located in a _config.properties file. In the table below, please see the description of most of the parameters:

Configuration.getInt(Parameter.BIG_SCREEN_WIDTH) //return int value
Configuration.getDouble(Parameter.MAX_DRIVER_COUNT) // returns double value

Environment specific configuration

In some cases, it is required to support multiple environments for testing. Let's assume we have STAG and PROD environments which have different application URLs. In this case, we need to specify the following properties in _config.properties:

env=PROD
STAG.url=http://stag-app-server.com
PROD.url=http://prod-app-server.com

And get an env-specific argument in the test in the following way:

Configuration.getEnvArg("url")

As a result, you switch between the environments just changing the env argument in the _config.properties file.

Tests execution filter configuration

The test_run_rules parameter is responsible for filtering tests. There are 3 filter types:
1) PRIORITY - enum field (from P0 to P6)
2) OWNER - the test owner
3) TAGS - custom label

Example of how to attach labels in code:

@Test
@TestPriority(Priority.P3)
@MethodOwner(owner = "Josh")
@MethodOwner(owner = "Jake")
@TestTag(name = "feature", value = "web")
@TestTag(name = "type", value = "regression")
public void t4(){
    ...
    some code
    ...
}

test_run_rules parameter parse logic:

1) A simple filter:

test_run_rules=OWNER=>Josh
#Where OWNER is tag, and "=>" split's tag and rule part.
#Because of the "Josh" rule, test will be executed if it has Josh as owner

2) With negative logic:

test_run_rules=OWNER=>!!Josh
#Test will be executed if it hasn't got Josh as owner

3) With boolean logic:

#Use || or && to create more difficult rules
#where || == OR; && == AND.

test_run_rules=OWNER=>Josh||Jake
#Test will be executed if it has at least Josh or Jake as owner.

test_run_rules=OWNER=>Josh&&Jake
#Test will be executed if it has at least Jish and Jake as owner

test_run_rules=OWNER=>Josh&&Jake||Peter
#Expression will be processed in sequential priority, like
#test_run_rules=OWNER=>((Josh&&Jake)||Peter)
#So test will be executed if it has at least (Josh and Jake) or (Peter) as owner

4) To add more tags to the rule, use ";;", for example:

#;; works as && (AND) but for tags

test_run_rules=PRIORITY=>!!P1;;OWNER=>Josh&&!!Jake;;TAGS=>feature=web&&!!type=smoke||feature=android

#Test will be executed if it has
#1) no @TestPriority(Priority.P1)
#AND
#2) @MethodOwner(owner = "Josh") without @MethodOwner(owner = "Jake")
#AND
#3) (@TestTag(name = "feature", value = "web") without @TestTag(name = "type", value = "smoke"))
        or @TestTag(name = "feature", value = "android")        

#In other words, tests will be executed only with Priority that differs from P1, with Josh as owner if there is no Jake 
#and if they are not for smoke web or if they are for android.

FAQ

Where is a recommended place to declare configuration parameters?

Declare default parameters in _config.properties. For multi-maven projects, you can use extra underscore symbol to override default settings on new layer __config.properties, ___config.properties, etc.

How to override params from the code?

Put method might be used to override parameters globally or for a current test only

R.CONFIG.put("selenium_url", "http://host1:4444/wd/hub"); //override selenium_url globally for the rest of tests
R.CONFIG.put("selenium_url", "http://host2:4444/wd/hub", true); // override selenium_url for current test only
R.DATABASE.put("db.driver", "org.postgresql.Driver") //override db.driver in_database.properties globally

Crypted values are returned in encrypted format. How can I decrypt them?

Use R.CONFIG.getDecrypted(String key) method to read decrypted value.

You should have valid crypto key to be able to decrypt values. For details, visit Security

Can I override configuration parameters from CI?

Provide updated values via System Properties to override a value, for example:

mvn -Denv=PROD ...
