What is CTX in BeanShell?

ctx. ctx is the most powerful variable exposed to BeanShell. It represents the JMeterContext class, which is virtually JMeter itself. It provides read/write access to the underlying JMeter engine, samplers, and their results as well as variables/properties.

How do you use a JMeter variable in BeanShell?

BeanShell vars. Create a sampler to request a product from the Amazon website. Then add a Post CSS/JQuery Extractor and extract the buying price. Whenever this request is executed, JMeter will create a variable on memory with the “Reference Name.” This variable is only available during that test.
