• component, helper, modifier helpers tests Adding helper, modifier, component helpers #85
• each inside each
• DOM builders (we could create known html tags)

• Cell (cell instances should work as primitives in templates (boolean,number,string)), could be used as attribute/property and condition (for if) and remains reactive cell and merged cell tests #34
• MergedCell should work as primitives in templates (boolean,number,string)), could be used as attribute/property and condition (for if) and remains reactive cell and merged cell tests #34
• effect (function should re-execute if related fields changes) effect tests #32
• modifier (it should run before document in dom and execute destructors if component is removed) modifier tests #33
• formula (tbd) cell and merged cell tests #34
• slots (if no yeild - no slots, default slot tests and multiple slots tests) slot tests #31
• conditional slots (slot with same name could be in different if conditions, we need to check how it's working) more slots tests #35
• @args (field types should match inputs - primitives, functions) args-tests #36
• class-based component (tbd) args-tests #36
• template-only component args-tests #36
• function based component (tbd)
• components with root node (tbd)
• components without root node (tbd)
