Load testing

1. A method performed by a processor of a computing device, the method comprising:

obtaining recorded lines of code of an application that are recorded as the application is executed in a client computing device;

performing a dependency analysis, including examining the recorded lines of code in a chronological order to determine variables in the recorded lines of code that are dependent on other variables in the recorded lines of code;

storing dependencies between the variables in a data storage; and

performing an elimination analysis, including:

in response to identifying, from the recorded lines of code, a first line of code including a network call statement that calls a called variable, examining the recorded lines of code in a reversed chronological order to identify a second line of code that contains the called variable and another variable,

based on the dependencies between the variables stored in the data storage, determining whether the called variable called by the network call statement is dependent on the other variable appearing in the second line of code, and

in response to a determination that the called variable called by the network call statement is not dependent on the other variable appearing in the second line of code, eliminating the second line of code from the recorded lines of code.

2. The method of claim 1 , further comprising:

in response to a determination that the called variable called by the network call statement is dependent on the other variable appearing in the second line of code, maintaining the second line of code in the recorded lines of code.

3. The method of claim 1 , further comprising:

obtaining a control flow graph (CFG) of the recorded lines of code, the CFG defining executable blocks of code and relationships among the executable blocks of code; and

determining a subset of the CFG based on a history of user interactions with the application, wherein the dependency analysis and the elimination analysis are performed in accordance with the subset of the CFG.

4. The method of claim 1 , wherein examining the recorded lines of code in the reversed chronological order to identify the second line of code comprises:

examining the recorded lines of code in the reversed chronological order starting from the first line of code until the second line of code that contains the called variable and the other variable is identified.

5. The method of claim 1 , further comprising:

presenting a subset of the recorded lines of code that remain after the elimination of the second line of code, wherein the subset of the recorded lines of code includes user-entered parameter data such that the user-entered parameter data is displayed visually different from the rest of the subset of the recorded lines of code.

6. The method of claim 1 , further comprising:

normalizing the recorded lines of code based on a programming language syntax.

7. The method of claim 1 , further comprising:

modifying the recorded lines of code that include statements that are specific to the client computing device or a browser of the client computing device.

8. A non-transitory machine-readable storage medium comprising instructions executable by a processor of a computing device to cause the processor to:

obtain recorded lines of code of an application that are recorded during an execution of the application in a client computing device;

perform a dependency analysis by examining the recorded lines of code in a chronological order to determine variables in the recorded lines of code that are dependent on other variables in the recorded lines of code; and

perform an elimination analysis by identifying, from the recorded lines of code, a first line of code including a network call statement that calls a called variable, examining the recorded lines of code in a reversed chronological order to identify a second line of code that contains the called variable and another variable, determining whether the called variable called by the network call statement is dependent on the other variable appearing in the second line of code, and eliminating the second line of code based on a determination that the called variable called by the network call statement is not dependent on the other variable appearing in the second line of code.

9. The non-transitory machine-readable storage medium of claim 8 , wherein the instructions are executable to cause the processor to:

obtain a control flow graph (CFG) of the recorded lines of code;

monitor user interactions with the application; and

calculate the CFG based on the monitored user interactions.

10. The non-transitory machine-readable storage medium of claim 8 , wherein, to examine the recorded lines of code in the reversed chronological order to determine the second line of code, the instructions are executable to cause the processor to:

examine the recorded lines of code in the reversed chronological order starting from the first line of code until the second line of code that contains the called variable and the other variable is identified.

11. The non-transitory machine-readable storage medium of claim 8 , wherein the instructions are executable to cause the processor to:

in response to a determination that the called variable called by the network call statement is dependent on the other variable appearing in the second line of code, maintain the second line of code in the recorded line of code.

12. The non-transitory machine-readable storage medium of claim 8 , wherein the instructions are executable to cause the processor to:

modify the recorded lines of code that include statements that are specific to the client computing device or a browser of the client computing device.

13. A system comprising:

a processor; and

a memory storing instructions executable to cause the processor to:

obtain recorded lines of code of an application that are recorded during an execution of the application in a client computing device;

perform a dependency analysis, including instructions that cause the processor to examine the recorded lines of code in a chronological order to determine variables in the recorded lines of code that are dependent on other variables in the recorded lines of code;

store dependencies between the variables in a data storage;

perform an elimination analysis, including instructions that cause the processor to:

in response to identifying, from the recorded lines of code, a first line of code including a network call statement that calls a called variable, examine the recorded lines of code in a reversed chronological order to identify a second line of code that contains the called variable and another variable,

based on the dependencies between the variables stored in the data storage, determine whether the called variable called by the network call statement is dependent on the other variable appearing in the second line of code, and

in response to a determination that the called variable called by the network call statement is not dependent on the other variable appearing in the second line of code, eliminate the second line of code from the recorded lines of code; and

cause a display of a subset of the recorded lines of code that remain after the elimination of the second line of code, wherein the subset of the recorded lines of code is used for load testing.

14. The system of claim 13 , wherein the instructions that cause the processor to cause the display of the subset of the recorded lines of code comprise instructions that cause the processor to:

detect user-entered parameter data in the subset of the recorded lines of code; and
