[build] build selenium manager for tests

[titusfortner]

Note: This code includes #16743 for it to work

User description

💥 What does this PR do?

This code fixed constant build churn by always downloading latest manager: #13314
But this doesn't work when you change selenium manager code locally.

Conditional is now

• if pin_browsers - download instead of build
• if stamp - download instead of build
• else build instead of download

@bonigarcia / @diemol does this look right to you?

PR Type

Enhancement

Description

• Conditionally build or download Selenium Manager based on build flags

• Download when using pinned browsers or stamped builds

• Build locally when developing Selenium Manager code

• Reduces build churn while supporting local development

Build

BUILD.bazel Add conditional build vs download logic for Selenium Manager common/manager/BUILD.bazel Replaced static download references with conditional select() statements Added logic to download when use_pinned_browser or stamp flags are set Added logic to build locally from //rust:selenium-manager-* targets otherwise Applied same conditional pattern to Linux, macOS, and Windows manager aliases +18/-3

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	✅ Prevent build failures from conflicting conditions Suggestion Impact: The commit addressed the conflicting select-condition problem, but by simplifying the select() mappings: it removed the separate "//common:stamp" and OS-specific keys and switched the default branch to build from source (//rust:selenium-manager-*) while keeping the use_pinned_browser override. This avoids the original overlapping-condition failure without introducing config_setting_group. code diff: @@ -13,9 +13,7 @@ name = "selenium-manager-linux", actual = select({ "//common:use_pinned_browser": "@download_sm_linux//file", - "//common:stamp": "@download_sm_linux//file", - "//common:linux": "//rust:selenium-manager-linux", - "//conditions:default": "@download_sm_linux//file", + "//conditions:default": "//rust:selenium-manager-linux", }), ) @@ -23,9 +21,7 @@ name = "selenium-manager-macos", actual = select({ "//common:use_pinned_browser": "@download_sm_macos//file", - "//common:stamp": "@download_sm_macos//file", - "//common:macos": "//rust:selenium-manager-macos", - "//conditions:default": "@download_sm_macos//file", + "//conditions:default": "//rust:selenium-manager-macos", }), ) @@ -33,8 +29,6 @@ name = "selenium-manager-windows", actual = select({ "//common:use_pinned_browser": "@download_sm_windows//file", - "//common:stamp": "@download_sm_windows//file", - "//common:windows": "//rust:selenium-manager-windows", - "//conditions:default": "@download_sm_windows//file", + "//conditions:default": "//rust:selenium-manager-windows", }), To prevent build failures from conflicting conditions in the select statement, use selects.config_setting_group to create a mutually exclusive condition.

High
Learned best practice	Centralize repeated select logic Factor the repeated select() mapping into a small Starlark macro (in a .bzl file) so the conditional logic lives in one place and OS-specific values are passed as parameters.
