Testing an ICBM I think will only happen after Kim Jong-un’s January 1st deadline to have a deal in place to drop sanctions. It makes no sense for him to do the test before then. Plus I only think he goes through with an ICBM test if he is confident that the Trump administration will not respond militarily:

Frequent movements of trucks have been recently detected at a rocket launch site in North Korea, a sign that Pyongyang may be preparing another long-range missile test.
“North Korea appeared to have renovated its missile-related facilities in Dongchang-ri [in Cholsan County of North Pyongan Province] earlier in the year,” a high-ranking official in the South Korean government told the JoongAng Ilbo on Friday. “And recently, we detected an increase in the movement of vehicles in the area.”
At least four vehicles including buses and trucks were spotted in a parking lot near a facility that tests engine combustion in a satellite image of the site on Nov. 1 provided by Google Earth.
“There is a facility used for testing engine combustion in the area, and we detected small buses and trucks coming and going there,” the official said. “The North may not be ready to test a missile immediately, but we see these as signs that it is getting ready for one.”
