Talvez deva tentar algumas variações de ortografia:
componente control » componente controle (Expandir a busca), componente central (Expandir a busca), complete control (Expandir a busca)
control programs » control program (Expandir a busca), control problems (Expandir a busca)
testing method » testing methods (Expandir a busca), costing method (Expandir a busca), casting method (Expandir a busca)
using testing » using resting (Expandir a busca), using nesting (Expandir a busca), ring testing (Expandir a busca)
method python » method method (Expandir a busca), python python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder AND componente control programs ) OR ( using testing method python programming ))~.
