Interpose processing is a feature that handles variable before and after the execution of measurement item. To create interpose processing, specify the process flow by interpose algorithm and specify process condition by interpose condition.
Here is an overview.
For more details, refer to this document.
Followings are the examples of interpose processing:
Interpose Process | Interpose Algorithm | Interpose Condition |
---|---|---|
Wait 2 seconds before measurement | Wait Time before Measure Item | Wait Time: 2 seconds |
Assign the measured value of I/O1 pin to specified variable | Store Pin Result Value | Pin: I/O1 |
CloudTesting Lab has basic interpose algorithms. Customers can develop interpose algorithm by themselves using Java.
Use standard interpose algorithm
CloudTesting Lab has following basic interpose algorithms.
Name | Process | Pre Interpose | Post Interpose |
---|---|---|---|
Set Variable | Assign the result of the expression to the specified variable | Executable | Executable |
Wait Time before Measure Item | Wait for the specified time before measurement. | Executable | In-executable |
Wait Time after Measure Item | Wait for specified time after measurement. | In-executable | Executable |
Store Pattern Result | Assign the result of function test to the specified variable. | In-executable | Executable |
Store Pin Measure Value | Assign the measured value of the pin to the specified variable. | In-executable | Executable |
Store Pin Result Value | Assign the measurement result of the pin to the specified variable. | In-executable | Executable |
Store Comment Measure Value | Assign the measured value of comment to the specified variable. | In-executable | Executable |
Store Comment Result Value | Assign the measurement result of the comment to the specified variable. | In-executable | Executable |
Develop interpose algorithm by yourself
If you want to develop interpose algorithm by yourself, you can do it by Java.
You can develop interpose algorithm in the following procedures:
(Use the command prompt)
Step | Procedure | Content |
1 | Install JDK 8 |
To develop using Java, install AdoptOpenJDK 8 (HotSpot) for Windows x64. Add JDK bin directory to Path to use JDK commands on command-line. set Path=%Path%;Path\to\JDK\bin |
2 | Create source code |
Create source code(.java). Inherit one of the following depending on the executing order.
|
3 | Compile source code |
Compile source code(.java) by javac command included in JDK. javac -classpath "%ProgramFiles%\CloudTesting\interpose\release\CTLab_Interpose.jar" -d . -encoding utf-8 Example.java If succeeded to compile, Java class file(.class) is generated. |
4 | Archive Java class file |
Archive Java class file(.class) by jar command included in JDK. jar cvf Example.jar com\* If succeeded to compile, Java archive file(.jar) is generated. |
5 | Place the Java archive file |
Place the Java archive file(.jar) to the following path: %ProgramFiles%\CloudTesting\interpose\custom |
6 | Use on CloudTesting Lab | Launch CloudTesting Lab on Expert mode. Added interpose algorithm will be displayed on the interpose processing list. |
Handle variables on Interpose Algorithm
To handle variables on interpose algorithm, use InterposeVariable class.
Followings are the readout methods.
Return Type | Name | Arguments | Description |
---|---|---|---|
Integer | getIntegerValue | - | Get the value of integer type variable. If the variable type is list, the value of first element will be returned. |
Long | getLongValue | - | Get the value of long type variable. If the variable type is list, the value of first element will be returned. |
Double | getDoubleValue | - | Get the value of double type variable. If the variable type is list, the value of first element will be returned. |
Boolean | getBooleanValue | - | Get the value of boolean type variable. If the variable type is list, the value of first element will be returned. |
String | getStringValue | - | Get the value of string type variable. If the variable type is list, the value of first element will be returned. |
Integer | getIntegerValue | Integer... indexes(*1) | Get the integer value of the variable at index. |
Long | getLongValue | Integer... indexes(*1) | Get the long value of the variable at index. |
Double | getDoubleValue | Integer... indexes(*1) | Get the double value of the variable at index. |
Boolean | getBooleanValue | Integer... indexes(*1) | Get the boolean value of the variable at index. |
String | getStringValue | Integer... indexes(*1) | Get the string value of the variable at index. |
List | getIntegerValues | - | Get the values of all integer type variables. |
List | getLongValues | - | Get the values of all long type variables. |
List | getDoubleValues | - | Get the values of all double type variables. |
List | getBooleanValues | - | Get the values of all boolean type variables. |
List | getStringValues | - | Get the values of all string type variables. |
1 Specify the index of list variable. If the variable is multidimensional array, required number of arguments equals the number of its dimension.
