This topic provides a brief overview of testing Qt applications with TestComplete.
With TestComplete you can easily test your 32- and 64- bit Qt applications. You can perform any kind of testing – unit, functional, regression and so on. The easiest way to create a test for your application is to record a keyword test or script routine. While playing back a test, TestComplete repeats all the recorded actions you performed over the tested Qt application during recording. If needed, you can also extend the recorded test manually using specific features provided by TestComplete.
TestComplete supports applications that use Qt library ver. 5.0 - 5.12 and that were created with Microsoft® C/C++ Optimizing Compiler. You can use the compiler shipped along with Microsoft Visual Studio 2010 and later to compile your applications. Qt library can also be integrated into any other IDE (for example, into Qt Creator).
There are also special TestComplete modules that provide support for earlier Qt versions. These modules cannot be used with the modules that provide support for Qt 5.0 - 5.12. They are not included in the TestComplete installation package. You can download them from our web site:
The package contains detailed information on how to install these modules in TestComplete.
|Note:||TestComplete does not support applications that use the Qt library compiled for static linkage.|
With TestComplete, you can record and play back user actions in Qt applications, or you can create tests manually from scratch. Usually, it is easier to record the test first and then modify and enhance the recorded test.
When you record a test, you interact with the tested Qt application as an end-user would: navigate through the application’s screens, fill out forms and so on. TestComplete captures all actions you perform in the application and adds them to the test.
A test consists of a sequence of operations that define various interactions with objects in the tested application. For example, in the sample test below you can see that opening a combo box drop-down list is represented by the
DropDown operation, checking a tool button - by the
CheckButton operation, and so on.
textEdit = Aliases.textedit.TextEdit;
def Test1(): textEdit = Aliases.textedit.TextEdit; textEdit.TextEdit.Keys("new text"); textEdit.ToolBar.ComboBox.DropDown(); textEdit.ToolBar1.ToolButton1.CheckButton(cbChecked);
Set textEdit = Aliases.textedit.TextEdit
Call textEdit.TextEdit.Keys("new text")
var textEdit : OleVariant;
textEdit := Aliases.textedit.TextEdit;
textEdit = Aliases["textedit"]["TextEdit"];
The recorded tests can be modified and enhanced in a number of ways to create more flexible and efficient tests. For example, you can:
Add new operations, reorder operations and modify their parameters.
Delete or disable unneeded operations (for example, superfluous recorded operations).
Insert checkpoints for verifying objects and values in the tested application.
Create data-driven tests that run multiple test iterations using different sets of data.

There are two major test formats in TestComplete:
Keyword tests - visually configured tests with grid-based editing interface. Best suited for novice users and those without programming knowledge.
Scripts - code written in one of the supported scripting languages. May be better suited for advanced users.
You select the test type when creating a test and cannot change it later. However, you can mix keyword tests and scripts within the same test project and call them from each other.
TestComplete also includes additional test types, such as low-level procedures, unit tests, distributed tests and so on. You can use them to address specific testing needs. However, most automation is typically done using keyword tests and scripts.
Each object in an application has a number of properties, such as its location, text, type and so on. Some object properties are persistent and unchanging, and therefore can be used to locate objects in applications and differentiate among various objects.
When you record a test, TestComplete captures all windows and controls that you interacted with during the recording session and adds them to the Name Mapping project item (also known as the object repository or GUI map). For each captured object, TestComplete does the following:
Selects a set of properties and values that uniquely identify the object in the application and saves them to Name Mapping as the object identification criteria. These properties will be used for locating the object during subsequent test recording, editing and run sessions.
Generates an alias (name) that will be used to reference this object in tests. By default, TestComplete generates aliases based on object names defined in the application by developers.
Automatically captures and adds images of the mapped objects to the Name Mapping repository. This helps you understand which window or control one or another mapped object matches.
The following image shows sample Name Mapping for a Qt application:
Here, the ToolButton object is identified only by one property -
QtText. This property specifies the object text as it is defined by the application developers in the application’s source code.
However, Qt application objects can also be located by other properties, such as their class name, text and so on -- whatever best identifies a specific object.
If needed, you can modify the default Name Mapping generated by TestComplete. For example, you can:
Change the identification properties and values to define more robust identification criteria or to reflect major GUI changes in newer versions of the tested application.
Rename aliases to more meaningful and descriptive aliases, so that it is easier for you to understand which object is which.
Manually add new objects to Name Mapping.
For more information, see Name Mapping.
Keep in mind that the object hierarchy in Name Mapping mirrors the object hierarchy in the tested application. When locating an object, TestComplete takes into account its entire parent hierarchy. If any object in the parent hierarchy cannot be found using the specified property values, the target object cannot be located as well. That is why it is important to select unique and unchanging properties for object identification.
TestComplete recognizes individual controls of Qt applications and lets you interact with them both at design time and during test recording or playback. In addition, it simplifies testing of the application’s user interface, since it includes special features used to test the most frequently used Qt controls.
For detailed information on support for Qt application controls, see Support for Qt Applications' Controls.
TestComplete makes visual objects of Qt applications available for testing, that is you can recognize these objects, interact with them and work with native members of internal Qt objects:
By default, TestComplete enables you to access all public methods from your tests. As for public properties, it can access only those properties of Qt objects that are listed in meta-information of an object and have standard QVariant-compatible data types. For more information, see Object Properties, Fields and Methods That Are Unavailable to TestComplete.
TestComplete can access protected and private properties and methods in Qt applications only if the following requirements are met:
Your application is compiled with debug information. For a detailed description of compiler settings, see the Compiler Settings for Visual C++ 8.0 and Later Open Applications (Unmanaged Code) topic.
The Enable Debug Agent and Read debug information for statically linked libraries options are enabled in the Project Properties - Debug Agent Options dialog.
|Tip:||Debug Info Agent™ is enabled by default.|
If all the requirements are met, TestComplete provides you with access to protected and private properties and methods.
For detailed information on how to address exposed properties and methods from your tests, see Accessing Native Properties and Methods of Qt Objects and Addressing Objects in Qt Applications.
To see what operations (methods) are available for objects in your tested Qt application, as well as the object properties and their values, you can use the Object Browser or Object Spy. The available properties and methods include those provided by TestComplete, as well as native object properties and methods defined by the developers in the application’s source code.
You can view the object properties and methods both at design time and at run time when the test is paused.
TestComplete includes a sample test project that demonstrates how to test Qt applications:
