What does it mean extractor children scope in Taurus?

问题

JMeter extractor in taurus have property scope(to check sub-samples)

https://gettaurus.org/docs/JMeter/#Extractors
scope: children

Could you explain what does it mean in example?

回答1:

When redirect is happening or if there are embedded resources JMeter generates so called "sub-samples" for them:

if you want to apply your extractor to the main sample only - leave the scope empty
if you want to apply your extractor to children only - set the scope to children
if you want to apply your extractor to the main sample and the children - set the scope to all

The above are just Taurus equivalents of JMeter's Post-Processors settings:

EDIT

From previous post the context is to include page(s) after redirect

Main/Sub samples are JMeter extractors concept

This is for use with samplers that can generate sub-samples, e.g. HTTP Sampler with embedded resources, Mail Reader or samples generated by the Transaction Controller.

Main sample only - only applies to the main sample

Sub-samples only - only applies to the sub-samples

Main sample and sub-samples - applies to both.

JMeter Variable Name to use - assertion is to be applied to the contents of the named variable

Corresponding values in taurus

Possible value for targets are:

all - main sample and sub-samples

children - sub-samples

variable for search in JMeter variables Default value of scope is empty, it means search in main sample only.
