About
You assign tags to features and scenarios to organize and run them by some criteria. For example, you can use tags to specify the operating system or environment in which the test should run, the browser that the test should check, the application subsystem or functionality that should be tested, and so on. You can then iterate through the list of features and scenarios, check their tags and run the features and scenarios that match your conditions.
Set a tag
You set tags in the Gherkin editor. Enter them before the feature or scenario description. Tags use a simple @tag
syntax:
As you can see in the image above, you can assign multiple tags, if needed. Simply separate them with spaces and make sure to put @
before each tag.
Notes
-
You can apply tags to the following Gherkin elements:
Feature
Scenario
Scenario Outline
(orScenario Template
)Examples
Test steps cannot be tagged.
-
Tag names are case-sensitive. For example,
@reports
and@Reports
are different tags. -
Tag names cannot include spaces.
-
Tag names cannot include parentheses.
-
A tag you set for a
Feature
applies to allScenarios
of thisFeature
.A tag set for a
Scenario Outline
(orScenario Template
) applies to theExamples
element in thisScenario Outline
(Scenario Template
). -
The
Scenario Outline
(orScenario Template
) elements can have multipleExamples
. By using tags you can run tests for a this or that set of data:Gherkin
Scenario: Test the Login screen
Given The Login form is on screen
When I enter "userName" and "password"
Then I should see "message"
@tag1
Examples:
|userName|password|message |
|user1 |pswd1 |Msg 1 ...|
|user2 |pswd2 |Msg 2 ...|
@tag2
Examples:
|userName|password|message |
|user3 |pswd3 |Msg 3 ...|
|user4 |pswd4 |Msg 4 ...|
Run by tag
Option 1 – Run from the UI
-
In the Project Explorer, right-click the project node, and then click Run @<tag_name> (if the Project Explorer panel is hidden, select View > Project Explorer from the main menu to display it):
This command will run all the features and scenarios that have the specified tag set for them.
Option 2 – Run as a test item
You can make a “tag run” test item and run features and scenarios by a tag along with other project tests as part of your project run:
-
Open the Test Items page of your project editor. To do this, double-click the project and select Edit > Test Items from the context menu, or double-click the project node in the Project Explorer and then switch to the Test Items tab:
-
On the tab, create a new test item.
-
Click the ellipsis button in the Execution entry column and select the desired tag in the subsequent dialog:
TestComplete will add the “tag run” to the test item list. It will run all the tests that match the selected tag when you run the entire project or if you run the test item to which the “tag run” is linked:
Option 3 - Run from the command line
To run feature files and scenarios by tag, you can use a command line like this one:
TestComplete.exe project-suite-file /project:project-name /test:"@tag1" /run
– or –
TestComplete.exe project-suite-file /project:project-name /tags:"@tag1" /run
For more information on other arguments, see TestComplete Command Line.
Run by tag expression
Some frameworks, like Cucumber, can run a combination of tags like @tag1 and @tag2
, or @tag1 and not @tag3
. To do this in TestComplete,
run your BDD tests as test items, or write script code that will check tags of features and scenarios and will run them from script.
Option 1 - Run as test item
-
Open the Test Items page of your project editor. To do this, double-click your project in the Project Explorer and select Edit > Test Items from the context menu, or double-click the project node and then switch to the Test Items tab.
-
On the tab, click New Test Item or New Child Test Item to add a new test item to your project.
-
Click the ellipsis button in the Execution entry column, and in the subsequent dialog, select [Tag Expressions]:
This indicates that a test item will run tests that match a tag expression.
-
To set a tag expression, click the ellipsis button in the Parameters cell and specify the desired tag expression in the Value cell in the subsequent dialog:
You can either enter the expression, or specify a project or project suite variable that stores the expression:
Click OK to save the changes.
Option 2 - Run from script
The script function below demonstrates how to check tags from script code. It iterates through the features and scenarios in your project and runs those features and scenarios that have the @Win10
tag assigned and don’t have the @LoginForm
tag assigned. The main function to run is RunByTag()
. The function that checks the tags is checkBDDItem()
. If you copy this code to your tests, re-write the checkBDDItem()
function to check the condition you need.
When checking tags, make sure to specify @
before the tag name.
JavaScript, JScript
// Run features and scenarios (@Win10 and not @LoginForm)
function RunByTag(){
// Iterate through features
for(i = 0; i < Features.Count; i++) {
var feature = Features.Item(i);
// Call a custom function to check feature tags
if (checkBDDItem(feature))
feature.Run();
else
// Iterate through feature scenarios
for(j = 0; j < feature.Scenarios.Count; j++) {
scenario = feature.Scenarios.Item(j)
// Call a custom function to check scenario tags
if (checkBDDItem(scenario))
scenario.Run();
}
}
}
// Check feature and scenario tags
function checkBDDItem(BDDItem) {
return BDDItem.Tags.Contains("@Win10") && !BDDItem.Tags.Contains("@LoginForm");
}
Python
# Run features and scenarios (@Win10 and not @LoginForm)
def RunByTag():
# Iterate through features
for i in range(0, Features.Count):
feature = Features.Item[i]
# Call a custom function to check feature tags
if checkBDDItem(feature):
feature.Run()
else:
# Iterate through feature scenarios
for j in range(0, feature.Scenarios.Count):
scenario = feature.Scenarios.Item[j]
# Call a custom function to check scenario tags
if checkBDDItem(scenario):
scenario.Run()
# Check feature and scenario tags
def checkBDDItem(BDDItem):
return BDDItem.Tags.Contains("@Win10") and not BDDItem.Tags.Contains("@LoginForm")
VBScript
' Check feature and scenario tags
Function CheckBDDItem(BDDItem)
CheckBDDItem = BDDItem.Tags.Contains("@Win10") And Not BDDItem.Tags.Contains("@LoginForm")
End Function
' Run features and scenarios (@Win10 and not @LoginForm)
Sub RunByTag
' Iterate through features
For i = 0 to Features.Count - 1
Set Feature = Features.Item(i)
' Call a custom function to check feature tags
If CheckBDDItem(Feature) Then
Feature.Run
Else
' Iterate through feature scenarios
For j = 0 to Feature.Scenarios.Count - 1
Set Scenario = Feature.Scenarios.Item(j)
' Call a custom function to check scenario tags
If CheckBDDItem(Scenario) Then
Scenario.Run
End If
Next
End If
Next
End Sub
DelphiScript
// DelphiScript does not support BDD functionality.
C++Script, C#Script
// Run features and scenarios (@Win10 and not @LoginForm)
function RunByTag(){
// Iterate through features
for(i = 0; i < Features["Count"]; i++) {
var feature = Features["Item"](i);
// Call a custom function to check feature tags
if (checkBDDItem(feature))
feature["Run"]();
else
// Iterate through feature scenarios
for(j = 0; j < feature["Scenarios"]["Count"]; j++) {
scenario = feature["Scenarios"]["Item"](j)
// Call a custom function to check scenario tags
if (checkBDDItem(scenario))
scenario["Run"]();
}
}
}
// Check feature and scenario tags
function checkBDDItem(BDDItem) {
return BDDItem["Tags"]["Contains"]("@Win10") && !BDDItem["Tags"]["Contains"]("@LoginForm");
}
For information on accessing features and scenarios in scripts, see Scripting (BDD).
Option 3 - Run from the command line
To run features and scenarios that match a tag expression, use the /tags
command-line argument:
TestComplete.exe project-suite-file /project:project-name /tags:"@tag1 or (@tag2 and @tag3)" /run
For more information on other arguments, see TestComplete Command Line.
Notes on the expression syntax:
-
Use
@
before tag names, that is, use@tag1
rather thantag1
. -
To combine tags, use the
and
,or
andnot
operations, for example:@tag1 or @tag2
@tag1 and not @tag3
not @tag5These operations don’t depend on the scripting language you use in your TestComplete project. That is, for example, in JavaScript projects you should use
and
,or
andnot
rather than&&
,||
and!
—@tag1 and not @tag2 ← Correct!
@tag1 && !@tag1 ← Incorrect! -
If needed, you can use braces to group tags, for example:
@tag1 and (@tag2 or @tag3)
(@tag1 or not @tag2) and (not @tag3 or @tag4)
Tagged hooks
Hooks are special script functions that run automatically at the beginning or at the end of a scenario or feature file. You can make hooks work only for those scenarios and features files that have the needed tags assigned. For complete information on this, see Tagged Hooks.
