Dynamic tracing of variables at runtime
A computer system may receive a user input associated with a source code file via a first user interface displayed a first computing device, where the source code file comprising source code of a software application. The computer system may then obtain a tracing configuration based on the user input, where the tracing configuration comprises a line number of the source code and a variable within the source code. Next, the computer system may set a breakpoint in the source code at the line number using the tracing configuration, and then trace the variable during execution of the source code, where the tracing comprises determining a value of the variable using the breakpoint in the source code and creating a call stack based on the execution of the source code. The computer system may then store the value of the variable and the call stack in a log.
