//! Regression tests for a whitespace-control regression in `java/assertion.jinja`.
//!
//! Every branch in the template used both a leading (`{%-`) and a trailing (`-%}`)
//! whitespace-trimming dash. With `trim_blocks`/`lstrip_blocks` already enabled, a plain
//! (non-dashed) tag already strips exactly the one newline that separates a tag from its
//! branch content; the extra `-` greedily eats all whitespace up to the next
//! non-whitespace character, which deletes the branch's own leading indentation and, in a
//! `{% for %}` loop, glues every iteration onto a single line (no newline is left between
//! them). These tests pin the corrected indentation and inter-statement newlines for a
//! single-line assertion and a looped (`contains_all`) assertion.
