expect_redux

Assert against Redux/Zustand store state at a path. Returns ok when the assertion matches; failResult with code=ASSERTION_FAILED when it does not. Operators (compose with AND): equals (deep), exists (default if no other op), notExists, length (array/string), contains (array), gt/lt/gte/lte (numbers). Pass timeoutMs to retry until match — useful when the store updates asynchronously after a tap. Differentiated capability over Maestro: Maestro asserts pixels; this asserts internal state.

equals	unknown	No			Deep-equal against this value.
exists	boolean	No			When true, value must be defined and non-null. When false, value must be undefined or null. Implicit default if no other operator is supplied.
notExists	boolean	No			Inverse of exists.
length	number	No		integer	Asserts (Array
contains	unknown	No			Asserts an array contains this element (deep-equal).
gt	number	No			Asserts actual > this number.
lt	number	No			Asserts actual < this number.
gte	number	No			Asserts actual >= this number.
lte	number	No			Asserts actual <= this number.
timeoutMs	number	No		min: 0, integer	Polling timeout in ms (default 0 = no retry). Useful for async state updates.
